first of all if you were in 'top 25 game wide' I would know your name. Secondly, if you were, you would put your highest arena score and state that you were a gladiator x times. I take you for a noob who just qq'd about how tough and unfair arenas are.
not sure what you are doing with the tab key, i use shift, ctrl and alt.
i guess no one needs the macro ability, its just something that makes the game more fun and competitive. Using macros well is a skill in itself. I still haven't heard a good argument for not having macros other than you are bad if you need them.
also to address paid tourneys. wow has them and often. I know for a fact that macros are allowed.
