if you use all your globals and get wow mechanics it will help. from a strategy perspective it will hinder you, as wod gameplay is very counter intuitive to anyone that plays wrath as the playstyle that wins games in wrath will make you lose in wod.
i blew my acl and had to drop out of pro athlete dreams and go to uni. after acl surgery I was given oxycoedine and used my school computer to play wow because it was really nice on the drugs.
i would just hang out and duel nonstop, then people invited me to play arenas with them after duels and we won a lot and got gladiator. if you are able bodied don't commit time to learning this game and getting gladiator, it is a waste but it was fun.
