Had an idea for a for fun, unbalanced game mode. Every hero in the match gets access to all their talents on each tier(either with or without both heroics). Theorycrafting on which heros would be the most broken was kind of fun.
Heros with multiple quests scale insanely funny, like Valla, Falstad, Thrall.
Mages like Mephisto/KTZ would do bajillion damages. Murky becomes unkillable demon king. Sgt. Hammer would be a nightmare.
Obviously this would be incredibly unbalanced and would just be a rapid mayhem mode only some people would be interested in(a good seasonal mode).
Idea came from LoL’s URF mode.
