Matches are pretty ridiculous after this patch I've noticed. With sometimes over 50% of a tier 5 - 8 team being composed of KV-# variants

When I saw the patch notes I started rejoicing that my elite M4A3E2 Jumbo Sherman had become the most heavily hull armored tier 6 tank.(with its nemesis, the KV-3 being promoted to tier 7) Alas I forgot about the French heavy ARL that sports a 120 mm frontal hull plate.
But at the same time I learned that armor is completely overrated as are good guns and high acceleration as I just bough a T20 medium tank at a bargain price.
I don't know why that tank is so fun to drive even with near-stock gear. When you look at its stats they seem abysmal for a tier 7 but I picked it up after I heard some recommendations and I must say I'm not disappointed. What's good about it is not in the raw stats but rather in some practical boons like a compact size, low profile and great turret versatility. But still I've had some wonderfully satisfying matches in the T20 by being more of a nuisance than a threat to the enemy with my low-penetration rapid-fire cannon. That will change once I upgrade the cannon to 90 mm.
It completely revolutionized my play-style after playing the E2 like a heavy for so long. With paper-thin armor you no longer care about the enemies penetration stats since all gun past tier 4 are guaranteed to pen you. Positioning is twice as important now though and driving along with the main battle line is out of the question.
I'm also satisfied with my choice of TD as with my SU-85 I now have exclusive access to the former KVs legendary 107 cannon at tier 5.
