1. In game we have only rear and front parts. In 99% cases you use it against frontal armor. Because in 1vs1 and 2vs2 you really don't have place for deep flanking to try to use it against rear armor.
2. Sounds nice but, while don't give just blitz? Because if this ability become skillshot like tullips, it also need to reward player for skill. Increase stun or effects on enemy armor? It only make things worse than now.
3. Ram can't be used right now if t-34 have engine damage from faust. Any counterplay also mean that you should compensate it somehow?
4. Because armor or T34-76 irrelevant to axis mediums it means only one - you should use RAm with 100% healt to get maximum result? Right now Ram just attempt to get some money from almost dead tank, when you know it don't have chances to live.
I never saw how someone use T85 ram. Really. Every player try to save such good tank, even in most desperate situations.
1- Because it's the easiest way to use it and there's no reason to try flank at all. If you hit the sides, you have a 50/50 in getting the rear armor, same with an out of position tank.
2- Blitz makes your tanks more mobile and agile while giving defensive or offensive boost. What i have in mind is a reposition tool which can be used to ram or cross a certain distance fast but have a drawback after certain time.
3- Ram can't be used IF you have engine damage but it can't be stopped if the ability has already started.
4- Ram is used at 100% HP on teamgames or 1v1 when we have heavy doctrine metas. Ram also works when you are ahead and the enemy has little AT and vehicles. When you have a resource advantage, if you can trade 1 for 1 you end up ahead.
