Use your ultimate to keep people away, the optimal time to use it is overtime on center.
in case of pushing the payload, you can put it in front of the cart.
Run a jump loadout with the card where Impasse knocks you up into the air. Use this to jump onto Kinessa, and then immediately cripple her with Treacherous Ground Warder's Field. She's very squishy and will have no means of escape.
Once an Andro tries to flank you, you should try to get one or two shots on him, then use your seedlings. He will most likely use reversal which gives you time to escape. This works best if Andro's escape ability is on cooldown (after he has flied)
Use Resonance against a Tyra. Her Fire Bomb will kill any clones you put on point anyway, so you might as well take Resonance so that every time the fire kills your clones, they explode and deal damage to the enemy frontlines.
