It's basically "Dude makes a whine post and suggest changes to the game" comprehensive list. I can't count the amount of times I've seen people suggest panzerschrecks for volks being changed and them being given a pfaust or the MG34 becoming a regular unit. (Even back when kubelwagon was a suppression unit) It's always been opposed because it would homogenize the game.
I'm no expert, but I think team weapons make the entire idea of combined arms interesting and thus should be accessible for all factions and should not be locked out in the name of "avoiding homogenization". Just my opinion.
I mean, both vanilla coh 1 factions had mgs and mortars that were kind of similar. Noone compalined. Yet the factions that tried to be sooo very different (PE and especially coh 1 brits) were a lot less popular. They had no conventional team weapons at all.
Team weapons are interesting and should be accessible IMO. There's other ways to differentiate them than to lock them in doctrines (MG34) or not integrating them (US Mortar). For example, in CoH 1 the allied AT gun had piercing rounds while the axis AT gun could cloak. The allied mg had piercing rounds but the axis one didn't. Stuff like that... but each role was filled. It didn't feel like sth was missing. I strongly opposse locking out what feels like it should be a basic part of a well designed faction just so it feels "less homogenized".
I was wondering why it sometimes would seem like the wfa armies are more prone to blobbing and not using combined arms? I think the inaccessability of team weapons could be part of the problem...
