Really loving Psylocke, it's like I've been training for her since Scarlet Witch and Emma Frost.
Lay down the vacuum orb to gather everyone up + -10% attack
Put down the circle aoe dot that slows dramatically
Then do a aoe melee spinning dive ninja thing followed by another spinning ninja twirly attack
Put down another aoe slow just because it's a mental ability which buffs my physical attacks (omega points spec)
These abilities work off each other buffing and doing interesting things, like healing me and giving me more hp. Which is why I could see what buffs are on me and stuff because I forget what's going on and what's down, but whatever, I'm doing enough damage and I'm staying alive I guess.
And spend some psi meter with brutal Psi Strikes for a bit (currently 13,800 - 21,000 x3 with +40% damage each consecutive strike). So deadly.
Fighting bosses is pretty safe and easy. I can put out the decoy if I'm getting my face mashed in to take off the heat, like Emma's pet with taunt. It's a low cooldown stealth so I can just keep doing it.
