The thing is Pyro, Hitech, us players can't always understand what happens on around us.
Strange things do happen - like others said, sneaking up on an enemy tank at zero range and blasting away a few shells, the enemy tanks doesn't explode.
It turns its turrets onto me, and then wham! one point blank range from his, and I'm dead. I'd understand if something like that happened from further ranges, but at point blank?
Granted, I've got no recording of it - it is admitably a rare instance. Also, most of the times the results are more or less satisfying - usually the first one discovers the other, and starts landing shells winning the battle.
..
However, in some of the strange occasions, (or even normal occasions..) the lack of visual representation of what happens around when two GVs engage just fuels the confusion even more. I'm not exactly thinking of a movie quality visual, but really, when all we've got is a graphic of a shell flying and a white glob of a momentary hit sprite... it's pretty damn hard to determine what's going on, or understand what is happening.
If there was someway we could perceive what was happening when we fire, land, and receive hits in the GVs in more detail, I think the complaints would simmer off a bit. Like, if we could tell that the round we've fired was a well placed hit, a bounced hit, or a just hit which unfortunately failed to penetrate.. something like maybe a well placed round giving off a hardy blast upon the target's surface, with bits and chunks of metal flying off... a bounced round which looks like it hardly done enough damage.. and a failed-to-penetrate round throwing off only a little bit of dust and smoke.. and etc etc.
And maybe if the visuals could portray the damages as seen in some planes in AH2 - like, crunched and battered metal plate which indicates the round hit but the armour held together.. or a largely drilled hole with messy blast rings around it indicating a penetrated hit.. and etc etc..
Also, we could use some better damage list - as in, if the round penetrated, which part of the turret with what component was damaged.. and etc etc.
..
What I'm saying is, ppl are making rash and hasty conclusions based on wrongly perceived string of events.. but their confusion itself is not entirely unjust - very little info for them to make judgements on, so its not surprising ppl come to wrong conclusions.
I just hope there's something better in stores for AH2 GVs to come

No doubt if HTC really makes a decision to implement something, it's gonna be great - (just wish that the decision comes quick!
