So, I happened to hit the same number of games played today on my T32 as on my T29. It's interesting to compare the stats:
The T32 has a better hit ratio, significantly more damage dealt (over 15% more!), and wins more medals. Yet the T29 has more kills, more wins, better survival, and more XP.
This seems to confirm to me what I said when I originally got the T32.
The T32 is a
good tank. 1v1 I can confidently take on any other tier 8 heavy, and many of the tier 9's. But overall, the T32 simply doesn't fare quite as well as the T29 due to the higher tier battles.
