5. Open the XComClassData.ini file with any text editor and search for lines that start with a +
They should start like this:
+SoldierRanks=( aAbilityTree=( (AbilityName="Stealth"),(AbilityName="RunAndGun") ....
+SoldierRanks=( aAbilityTree=( (AbilityName="Implacable") ....
6. Cut and paste Implacable where RunAndGun is and vice versa, save , and you're done.
Congratualtions, you just editted a mod! Keep in mind you will likely have to do this again each time the other mod updates as the file will be replaced by new versions that do not have this change.

tldr: Wacky skill order caused by mod incompatablilities, follow steps above to fix.

If you still want to have both this mod and the other, you can do the following:
1. Unsubscribe from this mod (you will be manually smashing this mod an the other mod together)
2. Verify the integrety of the game cache (https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335)
3. Delete the folder ${User}\Documents\My Games\XCOM2\XComGame\Config
4. Find the XComClassData.ini file for the other mod (it is C:\Program Files (x86)\Steam\steamapps\workshop\content\268500\{mod id}\Config),
-if you don't know the id you can find it by going to the mod page and looking at the url ex. this mod's url is https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id= 617943384
-if you don't know the mod, you can run a search for the file

I found out why woody, midknight, and I have had their skills all messed up when using this mod. Basicly we've had another mod that deletes lines in the Ranger class and replaces them with new lines, problem is... this mod will change 2 lines in the Ranger class such that they will no longer be deleted by the other mod, resulting in 2 sets of skillls that appear first in the skill tree. In my case the offending mod was SWR Hidden Potential. Steps to fix this in next post.

Same as woody. Perk tree is messed up. Squaddie gets implacable, corporal has run&/gun and bladestorm, sergeant has slash and bladestorm (again!). I don't have an Avenger save file with a Ranger higher than that.

So this doesn't work. It replaces slash with implacable, then it just gets more switched up from there.

I liked the idea of this mod, but it didnt work for me. So I gave it a shot.

By altering the DefaultClassData file, I have successfully altered the skill trees for the Ranger and Specialist. For the Ranger, I switched RunAndGun and Implacable. And the Specialist, I switched Scanning and CoveringFire.

If you open the DefaultClassData file, you will see the skill trees for all of the classes. All of these skill trees are easily customizable by simply swapping the names of the abilities you want to switch in the skill tree.

@littlenewbie
Huh. Okay thanks, I'll have to try and do that then. I hadn't bothered with the UDK yet I've been just modifying the base ini files (as it worked for me up until I started messing with abilities) and It's mostly fine but the first right ability slot on specialist is behaving oddly for me... I'll see if doing this through the UDK functions better or not. (Though it literally just appends ini changes into the ini files in 'my documents' as far as I'm aware so I see no reason why it would.)

added: Of course if that was the case I wouldn't think you'd need to remove the whole tree and re-add it... huh...

The only way I found to do this was to tell the game to remove all the skill tree entries for ranger. And then re-add them all. Here's what XComClassData.ini in the mod looks like: http://pastebin.com/8wuEZx1m

Heads up. If you use the instant-respec mod to use this one, then you cannot deactivate the instant-respec mod again so you're stuck with it D:

The more I think about it, the more this change makes sense. It really fits and helps make melee a more viable option. Realistically it is most of the time after melee kills where you will want to reposition since you will be standing in an awful spot. Love it.

@Azrail For my sword build, I don't need either Conceal nor Run and Gun. I do want both Implacable and Bladestorm though. So, this was my simple solution to this problem. :P

@Everwinter I think you can't have any Rangers who already have Lieutenant+ ranks selected before activating this mod since it does indeed delete the entirety of the old tree and replace it with the modified version. You can use https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=617916644 to respec all your high level rangers and then activate this mod.

@Azrail I would assume that its because you would get RaG at L.T. instead of Implacable, so that you get it a level early since RaG is like.. Ranger's bread and butter..

but why? not saying there cant be a reason but id like to know what it...

Actually I'm sorry for my horrible grammar and spelling I'm all mixed up right now. I didn't take bladestorm at corporal, I took blademaster. the whole tree got changed and is just wrong, I can't explain it all here.

This is broken, it made my descriptions for both seargent abilities disapear, gives me a choice between slash or bladestorm again for some reason. It also says missing template where the description should be when I hover over slash or bladestorm. If I choose bladestorm on the assault side it won't accept and nothing happens forcing me to choose slash which levels me up and gives me both slash and bladestorm (for a second time since I chose that the previous rank) highlighted under soldier abilitites. now I will need to playtest to see if I actually got Implacable or what happened...

Good idea but this is currently not working as intended.
