Except it doesn't. Not even close.
A damaged engine(Read: DAMAGED i.e. you can still move a reasonable speed) and a fully functioning main gun and coaxial + mounted MG means that tank is far from useless. It's just more vulnerable.
If you get caught by a snare when you're on the defensive, you're just not playing well. That's the long and short of it. If you can't reverse when you see a squad with a snare running towards you, it's your own fault. They lose a shit tonne of models and may even die trying to snare you. If you can't handle that then I can't really say anything else.
Once again, I'm talking about attacking, how would you attack with an immobile Tank?
A t-34/85 with damaged engine is of no use anymore if I want to advance towards my enemy. A Tank is an offensive weapon and the prepatch situation punished aggressive armor manuevers just beacuse a single conscript/gren squad could halt the whole push.
There's a military saying that states that an immobile tank is a dead tank.
I really do not buy the "killing flanking plays" explanation.
If killing flanks was such a gigantic issue they should shorten the range. Not make the ability hit or miss. The hilarious thing that you seem not to realize is that they didn't even fix the issue. It's still RNG, so it can still kill flanks.
Yes it can still kill flanks, but there is a reasonable chance of success. Before it was, if A then B now it's, if A then A, B or C.
As I stated before I think skill is to be able to evaluate risks and chances.
Also you should reread my previous post closely as well as what Fatal_Saint wrote.
All in all, I'm just no big fan of drôle de guerre like gamplay. There needs to be room for success for daring endeavours otherwise the game gets boring very quickly.
