Finally researched the T71. The last 30k xp on my T21 I just stayed back as anti scout for about half the match then went out and scouted and/or killed arty. Worked pretty good although I did die a lot. Most of the time in fact. The poor T21 is just weak. Weak armor. Weak gun even when using gold. Just weak. A shame too because it can be a fun tank at times. Anyway, I'm done with it. On to the next one.
