1) Can I say One Last Goodbye? Despite the misconception of them 'only being high rank because of pp' they're actually an amazing teammate. They're proactive and assist on pretty much anything.
2) MAD X; if it's the same team as previous worlds, or. . pretty much the same you can expect brute force coming from that source.
3) The Sleepless Elite / the land of the dead; Everyone noticed the growth from the start, typical rim-catchup setup. Remains tribeless and has yet to clash with anyone in the area looking at stats. So I guess they know what they're doing.
