Veterancy is broken again, that much I'm sure people understand. But you should know that we're actually worse off than from where we started, because Relic changed all the existing "apply_to_squad" veterancy that was working (received accuracy and sight bonuses, mostly) to "apply_to_entity", and this wasn't reverted, so now that they reverted the "apply_to_entity" code due to all the issues (rear echelon blobs etc), they won't work either.
Only remaining infantry veterancy is ability changes and conditional (heal outside combat, sprint outside combat etc) buffs.
Also annoyed of it, i mean there are in my opinion still a bunch of maps that are not balanced nuff or just a nightmare to play.
For example, Maps like Semioski and Moskau exist for a long time and have also changed multiple times but when you start north on thoses maps it's almost gg vs. good teams. - still not nuff vetos to veto this 2 maps for example, there are a lot more.
