w1 the scout is called winger_Scout? same with the shotgun soldier, being called Hunter_Soldier? the underscores look weird you could cut about 15 fan scouts, they're just a bit of a drag when nothing else is left on the field and there's still plenty that haven't spawned yet w2 has another case of slow ending, 40 soldiers that spawn really slow and there's not much going on with them giant battalion part is a bit of a tough customer, maybe cut one giant battalion? w3 the boss is a bit of a pain in the ass when he gets accompanied by conch and buff banner-boosted giants and steel gauntlets that force you back to the hatch at the start of the entire wave w4 generally from this point onward, the mission starts turning into a big cluster of everything which feels like you'd need Explode on Ignite and Projectile Shield to be able to hold any ground beyond the hatch (feels like 33-50% of the wave is active all at once) it becomes less "mission becomes difficult without a Heavy" and more "mission is practically borderline impossible to win" there's also a lot of slow progress going on because waves use infinite support too much (w6 is the best example of this)

Total wave time breakdown for: mvm_shiverpeak_rc2_advanced_fresh_frost [Failure] Time spent on Wave 1: 2 min 37 sec [Victory] Time spent on Wave 1: 3 min 25 sec [Victory] Time spent on Wave 2: 10 min 22 sec [Victory] Time spent on Wave 3: 5 min 4 sec [Victory] Time spent on Wave 4: 9 min 26 sec [Victory] Time spent on Wave 5: 5 min 31 sec [Failure] Time spent on Wave 6: 3 min 21 sec [Victory] Time spent on Wave 6: 13 min 8 sec Total success time in mission: 46 min 56 sec (88%)

wave 2 cut the soldiers at the end of this wave, they really take their time running in and it makes the wave last forever if you get pushed to hatch wave 3 feels like the entire wave is coming at us at once, there's so much shit going on also, all the cosmetics are probably causing some lag to happen, this and w2 lagged the hell out of me wave 4 lower the amount of demoknight inf support to 6, you have 18 bots using slots for Support 1 wave 5 halve the buff banner + burst demo squad, they drag on the wave for a good amount probably set the shortstop inf support to 4 instead of 5? wave 6 feels like you have the same pyro + land miner support on almost every wave of this mission and it's getting REALLY monotonous to see the same bots for almost the entire mission this wave is again going all the way with the bots the infinite support is using 31 SLOTS FOR THIS WAVE!! please overhaul the amount of infinite support you have going on, it makes this wave drag on like hell the buff + burst giants are a really anticlimactic ending to this wave, you can probably replace either one with a giant medic instead?
