The loop allows a full solo. If traya gained 1% tenacity (stacking) each time she was exposed while toppled, reset when topple ends. This would allow the team to still do some damage. If they test it and a fully G12 optimal team only does 2M or less damage with that change, make it a % chance to gain tenacity.
"Whenever exposed traya had a X% chance to gain 1% tenacity (stacking)" this way they can adjust X to find the sweet spot.
Sweet spot being where a team of max potency well modded and geared toons on a zfinn/3p0 team can manage 10-20% of P3 depending on the RNG of X.
Meaning that a team well geared and modded, could topple, run for awhile until her tenacity stacked high enough to resist the exposes, then as she is coming out of topple they could use CLS to stand alone, hopefully kill the sabers and topple again (resetting her tenacity) and maybe get a 2nd topple before she wipes them. Maybe even a 3rd topple! It would eliminate the infinite loop, leave the team viable, and not break any other part of the game.
