This is my new team.

[Pokemon Rejuvenation Viability Rankings Thread 4.0 [Community WIP] [SPOILERS]]

Noivern: B

+ Wide, high bp move pool that has good type and field coverage. ie hurricane is 100% accurate in rain, and boomburst gains effective stab power in caves where hurricane's power is nerfed.

+ Fast speed, passable sp. atk

+ Healthy set of resistances/immunities.

+ Serviceable in gyms that its available for, bar maybe angie.

- Very late evolution, lv 48. Noibat is effectively dead weight until it evolves.

- 4x ice weak

[Buff the Leaders]

I can see why some people might not like the field gimmicks. It's one thing to have a field effect boost type power, it's another thing to have them change the type coverage charts. With that said though, I definitely think the first 2-3 gym leaders were by far the hardest. Imo if any gym leader needs buffs, it's the latter ones. I accidentally beat the lastest gym fight even while 7-8 lvs under. It's not so much the gym leader pkmn being weak, it's more that in late game, player team comps finally get fleshed out which is a way bigger deal imo.
