You can re-position yourself out of the AoE of Willo's Seedlings using Rocket Boots, though you may end up sacrificing some Turrets and Barricade in the process.

It can be useful to bait him with your shield, and then use Rocket boots towards cover. Still an extremely difficult match-up, unless you have a DPS that is on-point with taking him out.

Try to avoid the fire bombs, as they can do large amounts of damage to your Barricade and your Turrets.

Normally a Drogoz will try to Salvo you as soon as you get to the point. Set up a Barricade to block it out.
