V4 changes
USF
Pak howi does not need a survivability buff. The 1 extra man is a quasi-buff. It should remain vulnerable to stukas and werfers. If anything, it needs an accuracy nerf and reverting the AOE nerf.
Officer change is a great QoL change.
M7 is quasi buff at best.
81mm mortar is a neutral buff.
The AA HT is a good change, it's pretty chaotic at AI, either suppresses instantly and wipes models on the move or static won't do anything. Great change all in all for the sniper countering.
Played a one quick game with USF and.... don't know really. Only change that is felt so far in all Versions are in the pak howi and scott. That's for 3v3 at least. Double mortars was much more successful than the double pak howi. Double mortars after the AT gun or weapon rack did much more while being cheaper and more maneuverable (retreat). Since the pak no longer has the AOE to scare away the blobs or static infantry, I can get the same effect for less with mortars.
Considering the games from V1 to V3: Every game I went scott I got owned. No matter how well I micromanage it, beyond the occasional barrage on some static emplacement, it was pretty useless. Even vs the 4x volks blob 2x scotts needed around 15 seconds or so to take down I think 4 models out of 20. I always attacked the first unit in the blob so that the shell lands in the middle of the blob. Pretty useless. The vetted scott (only managed to vet one scott) barrage is really really accurate. A good and a bad thing. Great vs an AT gun but bad in general damage in model rich areas. Still don't see a reason to go for the lieutenant in 3v3 and go for an M20. AA HT + AT gun is much more useful there. Stuart is more useful in 1v1 though due to the higher hp and less punishment if caught out of position.
That's all 3v3.
How the changes affect 1v1, I won't comment but I can definitely say that I did more dmg and wrecked more with double mortars as opposed to double paks I go in live game:
My build live that netted me most wins: 3 rifles -> ambo -> captain -> upgrade -> AA HT -> AT gun or weapon racks depending if I have rangers or not (3 zook delaying BARs and using AA HT to do the "heavy" lifting against LMGs and STGs + constant smoke to counter raketen and paks).
New 100% win build 3v3: 3 rifles -> ambo -> mortar -> captain -> AT gun/zooks -> mortar/AAHT -> etc...
Of course, depending on the game I either needed to delay the captain+ phase or rebuild.... All in all, mortars did much much more than the paks and scotts, had more damage in all of the 30-40 min games and bled less.
EDIT: Since I play random teams only, how it fares when it reaches live is to be seen since right now custom games are viable so...
