Honestly the reason tanks feel strong right now probably has more to do with Catch Up XP
Combined with strong base stats a counterjungler/early jungler can be ahead two levels but catch up xp is good. One mistake but the jungler in the lead and the tank is just as effective due to base stats.
Solution is to tweak catch up XP in a way that doesn't make non tank junglers non existant if they fall behind.
