Quite a few lfg-squads seem to fail at this, mainly because too many are focusing on it.
If you for example, push at the same time with Wild Blow and druid lb4, it can happen that the golem gets stuck or, worse, doesnt get pushed at all -> wasted 2 push skills.
Chrono veils being used after Golem was already pushed out, due to the "casttime".
Random pushes out of group back to mid because wild blow/glyph was used at a bad angle.
And so on.
So... what Ive seen work quite well... is putting down marks in four corners of the platform (NE, NW, SE, SW) and then let the chrono pull towards the closest mark, with druid/power slb using lb4 on quickdraw 2 times to throw off the platform. Epidemic is kinda needed if you dont have a dedicated pusher, otherwise golem will just wander back. Power slb with 2x lb can kill the golem alone, if you want an alternative to running with scourge. Both works just as well.
If your warrior ABSOLUTELY wants to push with wild blow, then let him push after chrono pull, with druid finishing off with lb4. But keep in mind, the more people push/pull, the higher the chance for golem getting stuck or pulled back or pushed randomly somewhere on the platform.
