My bad, I thought he was saying about 76 but SU, not T34/76.
That's what happens when you see only "76" without SU or T before
T34/76 is fine. Maybe little better AI but overall it's good.
At least I find them very useful.
When Relic "accidentally" reduced the reload time by a bit (which not one soul complained about) I think the T34/76 was in just the right spot.
