I like the crusader aura with 9 people to the node off to the side, while 1 rogue caps the first base (cos he can sap, blind, stun, disorientate people at the flag before needing to get hurt). Smash them all (fire eles and hero) at the first base, then surge forward and cap their closest base. Then win. Those who die go to the 2 rear bases.

It's kinda like a rush in arena. If needed, you go from the side node, half go back to close and half go to far node.

This strat is p much assuming most people go to either the close or side node, and not straight for the node on the other side of the map, and requires you to actually win a massive battle.
