The change to demo charges seems to have gone too far the other way. Their main role is wiping blobs (see 75% of all COH2 youtube videos), now that's going to be impossible, unless the person happens to look away from the screen (blobbers only have to focus on their blob).
Maybe lower the time to 1.5 seconds. Or experiment with having them lower the health as much as possible but not kill models. So instead of instantly wiping several squads, it drops their health to almost nothing.
As it is now I can't see it being very useful, and potentially means the Allies are vulnerable to Axis blobs all over again.
The problem with demo charges is that they are instant 'click' yeah I win and kill your lone squad capping ability. The funny thing is, OKW and all Allied factions are blobbing factions in 1v1 even. Meanwhile the multitude of blobbing factions (allied) have the actual best blob counter lol. Of course we can't neglect s-mines, but they can be spotted easily.
