A stacking tenacity mechanic while toppled would be so anoying too... One of my main P3 teams is based on termal detonators, with boba L, zam, dengar, greedo ang IG88.
I developed this team for that single purpose, cuz thanks to IG88 payout i can negate the tenacity traya gets from death sabers (3 ig88 hits in every topple is enough)... This team is fully potency moded and landing 10-15 detonators each topple +greedosstand alone net me 4-8kk damage in p3.
At least if something like that happens i got chewie without investing any extra shit in my BH cuz i had them alrready developeds...
