I'm very pleased to see that the update has reconsidered the weapon for the Partisan. MP44 is definitely not my first thought for a Partisan squad to have. MP40 is arguably not the most common either but it certainly is better. Now I tested them out with a few AI matches and here are a few things I've noticed about their new camouflage.
1) Even without any cover, they will remain camouflaged, but since they currently do not have hold fire, they will break out of their state as soon as they come within engaging distance (which is quite far).
2) Even when building, they will remain in camouflage. This means magical wires setting themselves up for the opponent as well as mines.
3) Any crew weapons they grab will gain the camouflage effect. Camouflaged Pak40, anyone? TWP OUTTA NOWHERE.
4) Weaker weapon made them a lot less "Run and GUn" but ambush based instead. Had a few tested scenario when they attacked by breaking out of camouflage close up (don't ask me how I got past the fact they didn't break out of camo before getting close, I used dark magic) and it is quite effective. Now imagine that with a mine previously set up? Squad wipes before the opponent can even react!
Should point 1, 2, 3 be kept how it is? Or is that too good to be true?
Edit: Personally feel that the Partisan should suffer the same penalty the sniper do from scout cars and such. They are similar now that camouflage is their unique advantage.
