There is a better solution then to ban people, and its not 'getting ahead in the game' its 'surviving a battle' as far as I know, you have to get out of dancing to attack, so in theory its not different then blocking. It seems stupid to ban people for using a glitch, so is it alright for a level 100 Sith lord to land ontop of Noob Planet for the Force and kill all the noobs there? Its fair because hes not using a exploit to win, hes just killing everyone.
Once again, it would be extreme cheating if you could also ATTACK while doing it, but if you have to leave your shield to do so, its not cheating, its suspending a fight.
Honestly people, can you see why I hate Bioware, they can write a good story, but have to use WoW's mechanics and ban people who find a bug in their perfect game.
