zFinn

He is tanky, has good dps, and his zeta gives 35% tm and reduces all cooldowns for all resistance members when damaging an exposed enemy. Because expose, stuns and tm reduction are some of the best negative status effects in the game and he and Poe synergize to do all three of those very, very often. Because he has team cleanse and heal over time for he and poe. Because resistance is one of the most easily farmable f2p factions. Because zeta resistance is probably the best p2 HAAT option. Because if a zeta resistance team goes first and exposes a toon, it is very difficult to stop them/ get a turn before they wipe you out.
