@DivineLucubration, @Beagle:

Not going to be able to sugarcoat what follows, so apologies in advance. In trying to write out suggestions and tweaks for the Rocketeer, it turned into a bit of a significant revamp. The original perk implementation looked like the class was confused -- is it a soldier highly trained to use a Rocket Launcher, or a Support Class who just happens to have a RL they can use at times. With a class name of Rocketeer, the spirit and intent would seem to indicate it wants to be the soldier highly trained with an RL. With that in mind, I came up with some ideas/suggestions that you might be able to use (or modify) for any future iterations of the class....

Tree Names:
Left: Blast Tech
Right: Field Tech

Rocketeer Perks
Squaddie:
Launch Rocket - The Rocketeer uses a rocket launcher to fire rockets. This allows for delivering large explosive payloads at greater range. The Rocketeer packs one High Explosive Rocket as standard equipment.

Corporal:
Shredder Rocket - The Rocketeer gains one Shredder Rocket as standard equipment.
Suppression (Pin them Down?) - Reduces Aim of the enemy target by 50 and triggers an Overwatch shot if the target moves. The suppression can be broken if the unit dies and sometimes when it receives damage.

***Shredder Rocket gets moved up and swapped w/ HEAT Warheads as their function really doesn't come into play until later in a campaign, but access to a 3rd Rocket this early would have an immediate need/gain. Also, pairing Shredder at this rank against Suppression will let the player choose if they want more explosions early on or some utility instead. Suggest a name change for Suppression due to the AoE/increased radius component that gets added w/ a later perk down the tree (DZ), should remove any confusion a player might get w/ vanilla Suppression which is single target only.

Sergeant:
Laser Guided - Grants +10 aim and +3 range (crit?) for all rockets if the soldier has not moved this turn.
Starburst - The Rocketeer launches a starburst bundle from the Rocket Launcher, causing a chance for all enemies w/in view to be disoriented (as if Flashbanged). 10 Turn Cooldown/Once Per Mission

***Renamed 'Fire in the Hole' to Laser Guided, as FitH seems more synonymous with a bigger explosion and not an aim/range boost. An additional suggestion would be to change the range component to crit chance/damage instead -- there are no other damage increasing modifiers in the perk tree, but there is a range increase further down. Starburst is the first revamped perk, it replaces Rapid Reaction. It still lends toward a support role, but puts it on additional use of the RL instead of a Rifle/SMG, and seems more like something a Rocketeer might have in their arsenal.

Lieutenant:
HEAT Warheads - All rockets gain +3 armor penetration (+6 with Advanced Explosives).
EMP Warheads/Pulse Tech - All rockets now cause an electromagnetic pulse upon explosion in addition to doing their normal damage. The pulse has a chance to stun/disable mechanical enemies.

***HEAT Warheads moved down from Corporal to this tier, as you should start seeing armored foes about the time you get a soldier to this rank. EMP Warheads/Pulse Tech is another ability revamp, it replaces Ready for Anything. RfA seems more for a full Support Class, not something a Rocketeer would be doing. Instead the EMP/Pulse Tech gives an
alternate option against HEAT, and is flavored for a class which has a RL and wants to use it!

Captain:
Salvo - Using the rocket launcher or a heavy weapon as your first action does not end the turn.
Tactical Rigging - The Rocketeer can carry 1 additional HE rocket and no longer suffers a movement penalty while carrying a rocket in their utility slot.

***Salvo works for this class as it does for the Grenadier, no more need be said. Tactical Rigging is another perk revamp, it replaces Opportunist. Opportunist is another perk that seems more suited for a full Support Class and not a class specialized/trained to use a RL to full advantage. However, a more advanced Rocketeer should know how to pack their gear to optimize capacity and movement in the field of battle, thus the idea behind Tactical Rigging. Math assumption here is that rocket count would not exceed 4 -- 1 (base) + 1 (utility) + 1 (shredder perk) + 1 (TR perk).

Major:
Danger Zone - Increases the area of effect for Suppression (Pin them Down) and explosives. Gain +2 explosive radius, and +3 suppression radius.
Advanced Tubing - Rockets now travel 33% further and are 10% more likely to hit their intended destination.

***Renamed 'Javelin Rockets' to Advaned Tubing and gave it a slight AIM boost, having just the range increase seemed lackluster when compared to the benefits provided by Danger Zone, even if the player hasn't chosen Suppression at Corporal (Lieutenant originally), the extra radius on explosions would usually appear more suitable overall (for a class firing rockets) leading to JR not being chosen much. Swapped the perk positions in the trees due to flow.

Colonel:
Bunker Buster - Launch a high payload H.E. Rocket with an increased blast radius. The Bunker Buster breaks through obstacles in its path before exploding at the point of impact. Consumes 1 HE Rocket.
Golden Eye - Launch a high yield EMP Rocket with an increased blast radius. Greater damage is inflicted upon mechanical enemies, and all enemy weapons caught in the blast will become disabled (must be reloaded). Consumes 1 HE Rocket.

***Revamped 'Double Tap' to Golden Eye -- again, a Rocketeer using a weapon/action at this rank w/out the use of the RL doesn't seem to fit with a class specialized/trained to use it. Also, very hard to see many players choosing Double Tap over Bunker Buster as they compare to one another....and the concept of Golden Eye adds more flavor and just sounds fun!


GTS Perks -- No changes suggested, although Weapon's Team does sound interesting -- is this meant to be an ability added to all soldiers, or something only given to another Rocketeer? Both perks are under Captain (assume typo).
