Trib is super easy to melee burn, just try to keep hate on one DPS to stack the fetters and zerg him down. You really don't need SPs for him but he has a hard 3min window.
Gertell is more of a pain, use all SPs and move away from the fetters. RUN really helps here since with wind hand he can steal some strong buffs but nothing Battula and a strong Hybrid RUN can't handle. You are racing against his DT build up, but he's also kite-able as things get hectic.
