The leFH must be nerfed.

KRZYBooP: I can't stay quiet! This is my favorite tank!  Can it be bananas in lower tiers? Yes, you bet.  Is it bananas against tier 7? NOPE! It doesn't even have a tier 6 gun to benefit from splash or HE, and in my opinion, never get one cause that would make it bananas in tier 7 with tracking potential.  It also can go against wheeled tanks which spot it and kill it in no time. (I know cause I have to play with that in mind when picking a spot to rain my hellfire.) It also is up for indirect nerfs that include changes to ammo and other general game mechanics.  These are my opinions and observations for why it is fine.
