I understand the thinking behind this, but I also disagree with what it promotes. I thought the whole point of Stage 3 was to test these suspects together in the standard OU metagame. In every metagame, teams are created to counter and stop all of the threats. If everybody only opts to use the suspects, then that creates a very artificial environment than what things would really be like, should they be in OU.
I think that if you are able to be successful on the ladder without even using most of the suspects, that still says a lot about your understanding of the suspects and how they may be stopped (or, if they are so blatantly uber, how they can't be stopped). If everybody is whoring out every suspect, just so that they can vote, then we're just seeing which suspects beat which suspects, and if anything, I think that gives you less "real" experience on how they would be in an OU environment.
IMO, people should use what works. If everybody started only using what worked instead of all of the suspects, then of course certain suspects will not get tested as much as others, due to some just completely outshining others. However, this should not be a big deal, because that means the less-used suspects will most likely not be voted uber (why should they be voted uber if they weren't even good enough for people to want to use them?) and be re-tested with the uber-voted suspects gone.
Just throwing my two cents out there. I know you guys have an intricate SEXP equation all fleshed out and I don't mean to demean it or anything. I appreciate all you guys have done to help this community out, but I think you should consider this.
Thanks for listening.
