Because the topic of this thread is specifically addressing the 'HE rounds' of that T4. If the shell is crap, which it sounds like it is, then this addition is pretty much 'nothing' compared to what it was before it was added, being the elite crew with MP44, Focus Fire and sniper/mortar buff.
Now an interesting idea I just thought of, being this is 'terror' and its 'heavy' support... what about giving AP shells or something to make it a heavier pak gun compared to normal wehr company paks? Since some people seem to be complaining of the pak's low damage against 57mms, 57mms with AP, and 57mm with TR AP?
what im saying is that you're calling the T4 crap because this isn't as good as Tank Reapers. It's meant to be part of the T4, if you make the ability as good as or even close to tank reapers, you're making the whole T4 better than Tank Reapers.
