Imo, if your oponent will agree with this trick u can use this tactic, why not?
Because if you allow that, all clanners will be 1v1 except TTRR, bungeerace and comet dodging.
Exactly how will a 2v4 scenario be beneficial in elite ? The worms may very well have a much faster rotation but that advantage can easily be overcome. Simply make sure that all 4 worms can reach each other so that telecowing will not work (Or at the very least girder block and then reach) besides unlike hysteria there are only 2 teleports in Elite.
Everything should be fair in love or war..As long as you don't use dark magic in order to summon uncanny powers (Like an aimbot or other exterior program intended to manipulate the game in favor of the user) everything else is or should be fair. If a clan will benefit by having the weaker player suicide himself out of the game so the stronger player can abuse turn order then that should be allowed.
The fault really lies with the fact that such a scheme is taken seriously in the first place (Hysteria). I likewise think that glitches should be allowed unless they are too gamebreaking such as that girder kill glitch from WWP.
