Rebalance base stats of Pokemon so much more of them are considered competitively viable.. (Like Gardevoir).
Drizzle and Sandstream Nerfed, either they only last as long as the Pokemon with the ability is out and alive or they last the normal 5 turns the Move version would have caused.
Stealth Rock nerfed in damage and which Pokemon can learn it. Transferring from old games would delete the move. --- 1. The only fool bigger than the person who knows it all is the person who argues with him. 2. They're all complacent sheeple. <==]-<(-_o)>-[==>
Weavile's stats are actually not terrible, it's his move set that's really terrible, as a glass cannon he lacks the punch or correct type attacks to OHKO the high attack, high speed, AND bulky Pokemon that occupy OU. It probably could use some more defense.
Also, Weather Teams murder him, as weather teams overall are OP.
I would argue there are quite a few OU Pokemon like Garchomp (102 Speed, WTF?), Conkeldurr, Excadrill, Tyranitar, etc. that need a base stat nerf, but that's a touchy subject. --- 1.
