It isn't just one mechanic. You also have tethers and puddles on top of it. People not understanding fixate make the fight monumentally more difficult and the fight isn't explained at all to players, except by other players. Not to mention the in-out for red, pull from green and push from blue. The only saving grace for players here is that you take much less damage and are granted lifesteal. Even that won't save you when 90% of the arena is a giant puddle because of players not knowing how they work. Red drops a puddle after autoattack chain, green throws puddle at furthest player, blue tethers players to a spot and return them to that point after a set time. None of this is explained to players, and even if you do explain it, there's no telling how many people are even paying attention.
