Yay one liner uninformed posts with dumb arguments. I almost want this thread to lock now.
NO ONE cares what banning an ability will do to a pokemon's viability. In fact, their overwhelming use and uncompetitiveness led to this thread being made to suspect the ability in the first place. The fact that trapinch is viable in OU at all, let alone a annoyance that can trap and murder walls, is even more testament to how broken arena trap is. It's even better off if it gets banned and drops it's usage, since it has proven to be so uncompetitive that a LC pokemon with a terrible BST is being used in overused frequently.
To be clear, I do not have a bias against anti-ban supporters in the forums. However, most of their posts are either uninformed, nonsensical, flat out wrong, or ad hominem. These people are causing toxicity in the threads, much like AT is causing toxic behavior in the OU community. This is going to devolve into a shouting match if no one intervenes, and all over a pokemon ability that the vast majority of the community is voting ban on anyway.
OH WAIT, Finch DID intervene. No one listened, they all kept parroting around "oH ArEnA tRaP iSn'T tHaT bAd" without giving an explanation. This thread is full of stupidity.
First and foremost, Shed Shell. It is an atrocity that any pokemon should have to run this instead of an actual item, just so they can check dugtrio. No wait, scratch that, TRY to check dugtrio. More often than not, it will get knocked off, or the pokemon in question will just die. There goes your one check and now a team of FIVE pokemon is weak to one. Shed Shell is not a anti-ban reasoning, it's a pro-ban on the basis that people felt the need to run it.
Second, Dugtrio's supposed low effectiveness. The way arena trap works, they switch it in on a pokemon weak to EQ. It dies. The enemy attempts to outspeed or flying type rush it. Duggy runs sash and claims another kill, using stone edge for flying types. Then dugtrio can die, since it doesn't have much purpose, unless you wanna spread condition or abuse regenerator or tank a hit or- yeah it's so versatile and useful despite having only one ability/gimmick.
Third: pokemon that aren't trapped. This is completely and utterly stupid. Almost anything untrapped will die. Pelipper, Heat, Mandibuzz, and Togekiss die to stone edge. And trapped are worse. Zeraora can only dent it's focus sash and die to EQ, and Excadrill and Toxapex are OHKOed and 2HKOed respectively, and the ghost type switches Gengar and Aegislash die to EQ as well.
Every single arguement on anti-ban is ridiculous and uninformed. Please Ban Arena Trap.
