Healthstones in the ArenaFollow

it'd work in some situations. but usually you want to vary the classes in your arena team. though i could see 3 afliction locks, 1 Shadow priest and 1 disipline/holy priest being a VERY powerful combination due to 5 instant cast aoe fears. 4 silences and so many dots it'd make any grown man cry the moment they saw the team :P

well in most scenarios. the insta gibbers can be instantly CC'd through aoe fear except for warrior heavy groups, but tbh, even an insta gib combination would have issues as they'll at best beable to get 1 person down instantly, after which the pretty much constant stream of dots and drain life /mind flay / aoe fears would ***** them over as well as being able to handle 2 healer combinations with little to no issue due to so many interupts and silences.

In computer games, gibs is short for giblets, small chunks of your opponent.
To gib someone is to overkill them so they break up into small pieces (like with a rocket launcher). So I'd guess they mean to nuke someone down extremely fast.
