Pockets proposal is superior.
Everythings supposed to be tested. It's figuring out what is the problem, and then acting accordingly.
I'd prefer it extended to more then just weather but any field effect where the conditions apply trick room, magic room, wonder room, etc if they are ever in the future (likely not this generation, but who knows what a move tutor could cause) found problematic.
I highly suggest rereading Pocket's proposal, as you don't seem to understand that its intent isn't to immediately ban Drizzle and all Swift Swimmers, but ban different aspects of Rain, then unban them and ban different aspects of rain, first banning swift swim, then unbanning the ability but banning the main abusers of it, then either banning Drizzle and unbanning the Drizzle abusers, ban ability combinations (such as Drizzle and Swift Swim) on the same team (basically Aldaron's proposal), or outright ban Politoed. Eventually this would hopefully lead to finding the most desirable and balanced metagame.
you both have far too much faith in people
You whatl happen?, this, in the first phase without swift swim people will go like "yeah, this is fun were not getting overwhelmed by these swift swim guys in perma rain anymore, lets just keep it like this and screw all the other phases in the proposal", and that will be that. You really think that if things are fun after the first phase people would want to put through 2 more months of testing?, of course not, people will say its a waste of time.
Id rather just start out with Aldaron's proposal, Swift Swim and Drizzle will be unable to be combined and then you what will happen?, people will say "cool this is fun, im not getting overwhelmed by these swift swimmers in permanent rain anymore, awesome", and taht will be that. Issue will be over and nothing will be banned.
Aldarons proposal appeals to me more because in the end Swift Swim will still be allowed use with a regular old Rain dance team, on the other hand on pockets that will probably be unavailable for the rest of gen 5, why?, because people will not want to go through 2 more phases if the first one turns out to make things fun.
thats why i view Aldaron's as superior and completely and utterly
condemn pockets proposal, screw that. People will not wont to bare 2 more months of testing and then a rain dance team with swift swim (that does not use Drizzle) will be gone forever
