Sometimes it happens that you get supressed even in cover, the suppression may rain upon you from the skies in form of panzerwerfer, you get flanked by mg or simply one stray soldiers stays out. Is it justified to punish RA of well designed defencive strong point just becouse part of it gets supression? I think it's horribly wrong.
(1) Models straying out of cover is something I haven't seen since the patch that was designed to solve it
(2) I'm not sure one would call it a well designed defensive strongpoint if a Panzerwerfer barrage manages to cover a number of units simultaneously. It punishes that kind of positioning now, and would continue to work like that afterwards. And any map enables a player to be smart with positioning
(3) I'm not familiar with technical design of RA but there could/should be distinction between small arms RA and HE RA, meaning my suggestion is kept to RA from HMG fire
On this forum we spend lots of time explaining to newer players the importance of spreading out their infantry and flanking. This debuff would ensure that advice finally begins to make sense to them.
