I love the KV4. Is the KV4 Kresl. a good upgrade/worth it?

Draschel:  While not great, KV4 is  -NOT- out of meta. This is not to say that KV4 constitutes a great part of current meta, no. But it isn't wholly left behind by meta. KV4 has been greatly buffed, and is definitely better than decent tanks such as Tiger II, Lowe, Liberte. It isn't prohibitively slow, front armor may not be great but it has forgiving armor thickness all angles, the pen is excellent, DPM is great. Its presence, HP, gun simply cannot be underestimated by even tens - it has better pen and DPM than Renegade
