I want to address a couple things that people have been debating about lately with my opinions on the matter.
Mega Sableye:
The no-ban argument saying it has no counters is basically bullcrap. Let me quote this directly from ginganigga in the suspect thread etiquette thread:
if something DOES have checks and counters, this doesn't make it NOT broken either
Mega sableye has plenty of counters, but it still is extremely overcentralzing, making certain Pokemon plummet in usagw such as mega gallade because they are shit against megaeye unless they use gimmicks(skill swap). Clefable is a counter to many common sets, but there are 5 other team members that can deal with it. Heatran + megaeye is a super common stall core that basically deals with all the fairy types that plague megaeye bar azumarill, and it can be burned by both of those mons, rendering it practically useless. Most smart stall players can add a couple mons to deal with sableye's checks and counters very easily and still have several slots to use because it's so good. In my opinion, mega sableye isn't broken, but it is definitely overcentralyzing enough to warrant a suspect test and a possible ban. Sure it isn't as borked as the 2 mons that have been banned in ORAS so far, but it is still suspect worthy mon and the meta would be significantly more healthy anyways.
Shadow Tag
NOT GOTHITELLE:
I personally think that shadow tag should be banned because it is extremely uncompetitive and requires basically no skill to use and is cancerous. You can be forced into lose/lose situations where you either get rid of your only hope against a sweeper that is left or let gothitelle destroy your team. It takes away one of the most integral parts of the metagame: switching. If you want to respond with an argument to this being flat uncompetitive I challenge you to.
Baton pass:
Since most people think that boosting pass is the broken part of this move, I just think that smeargle+baton pass and scolipede+baton pass should both be banned. Baton pass requires no skill to use, and very poor players can win using this strategy. Smeargle just has to come in on a slow Pokemon and put it to sleep the first turn, then it has to click geomancy to win the game. Scolipede basically has to come in on the right mon and click SD, then protect and baton pass in the following turns to pass 2 dragon dances to any team mate to make it OP. I honestly hope that this strategy is banned because it is more cancerous than it has ever been.
Talonflame:
The biggest thing that is a problem with Talonflame is that it can only switch in once or twice before it dies unless it has hazard clearing support, and that support can't always be provided if the opponent provides enough offensive pressure or has bisharp in case of a defogger. Talonflame can also be walled by basically any physically bulky rock or water type, and Heatran. The counters argument actually is significantly more viable with Talonflame because it can only switch out against a counter one time before it becomes death fodder, assuming that it has no attack damage on it. Talonflame is an excellent threat and many Pokemon would be better if it was not in the meta, but it isn't powerful or cancerous enough to ban.
These are just a few of my opinions on common discussion topics, and I may add a few if I forgot something that people are debating about.
