I haven't played it yet, but I really hope those nades aren't going to be over buffed. OP wipe thing nades like Guards and Gammon Bombs are horrible for Game play. I'm also worried about the best infantry based AT squad in the game being able to force away tanks then wiping Support Weapons AT guns with ease because of the nadesm
From the games I've played yesterday and a single toss I managed to do, it didn't do that much, but the squad I've tossed it at was quite spread out.
Will need to test it more, preferably on squads clumped up more.
However what you definitely can feel is the lack of crush, there are certain situations where meds just feel helpless.
Remember the times when single Tiger/IS-2 run like a puss from single con/gren squad, terrified by the AT nade engine damage? Well, we're right at this situation again for meds.
I feel for cromwell most as the target size change has a huge impact on shrecks accuracy and tank right now feels average at best.
Sherman though excells with its HE shells, other armor needs to run as soon as there is more then a single AT squad.
