I've been boxing 3 locks for PvP purposes as an introduction to boxing (along with 6 other sets of toons for PvE) and I must say I haven't had this much fun in WoW for a long long time.

I had them as demo but switched to aff to attempt a strategy that I saw a horde boxer doing a long time ago.

He had 5 aff locks and would sit behind the alliance GY and simply DoT everything that spawned with 15-20 DoTS whilst his team would run the flag back and forth.

I ran across another 5 boxer destro lock in IoC doing much the same thing. The Alliance had allowed horde to knock down their wall and cap their GY in their keep, then they ran out from their bosses room and farmed them in the GY with shadowfury and 5 x reign of fire, it was a slaughter.

I think if you're looking for maximum impact in a BG and for almost invulnerability, even against the genius of other boxers, warlocks are the class to go for.

I don't respect you any less for losing to him...just go for the other 35 members of the enemy team next time :P

And yes, Kromtor hit the nail on the head with his 'anti-fear berserk' comment
