I liked the dire orb trick on ztn for dropping on the mega, and the aiming at the feet to increase tele frag potential. Though I think the latter will be toned down in future as its a bit over powered.

I think its worth noting his teleport can be a good way to get out of quad area too; once you've collected it, fire it away just before it spawns, then if you get quad, teleport away, 9/10 there will be at least 3-4 players all wanting the same thing, even if you get it, you'll often die, or eat so much damage even if you kill those around you, you won't be in the best state to go quad hunting.

IMO letting those opponents to fight among themselves while you can teleport away with quad and a healthy stack will get you a bigger return by maximizing the power up which in FFA, once you reach a certain level of skill, is often the deciding factor in who wins games.
