I wonder, why Double Team is bannned to Evasion Clause, but para-fusion isn't deemed 'luck-based'...?
Honestly, most of the posts FOR SR only seem to reinforce why it should be removed from the metagame. Each and every post seems to make one of two points;
1) Either every team out there should have it, it has absolutely no downside what-so-ever, it gives you a distinct, possibly game-winning advantage for using it, and if you can't deal with it, don't play (which to me, qualifies as broken), or,
2) The fact that it makes pokemon weak to it die after two switch-ins without even being directly attacked just makes them bad pokemon, rather than making SR a broken move, and it's okay because people are too sick of it for it to be a big deal this gen.
When you can break down team roles into Hazard Layer, Hazard remover, LeadTaunter, and SpinBlocker, all based soley around one single move, and each team needs at least one of those roles, if not more, I think that's over-centralizing. When people can easily opt out of SR for spikes because most players are too uncreative to run fliers out of fear from SR, it's over-centralizing.
When it comes right down to it, SR and entry hazards in general are moves that are favored by a brutal, quick-paced metagame full of players who want their matches to feature the same pokemon and last 5 minutes tops. It renders a lot of pokemon useless, and encourages the all-too-metagame-defining 'force the switch' playstyle, which is almost entierly devoid of skill or stratagy, in favor of pre-scripted warstories about how cool you are for taunting their SRocker, setting up your own, and switching to your ghost-type when they switch to their rapid-spinner. You might as well just pull out a calculator and do some math homework while rolling dice, because that's about as much skill and thought things like SR brings competative pokemon to.
Nobody NEEDS SR, unless they just simply aren't confident in their ability to actually play without it, becuase their beloved OU pokemon fall flat in their ability to OHKO without hazard support, and get knocked out proptly by a nice sturdy tank. I play with Item Clause for the same reason; most players don't know what to do when they can't rely on Leftovers or LifeOrb for their damage calcs.
