Is summoning Tiche, and then running around the ring in circles, avoiding the boss, fun?

It is a way to progress in the game, which is fine, but I'm not sure who would consider that a "fun" experience.

I'm not saying that you need to melee-only, solo every boss in this game. Summons are a useful mechanic in this game. However, they are supposed to take pressure off you, and make beating the boss easier, not beat the boss entirely on their own.

This is why From nerfed the Mimic damage. It isn't supposed to literally solo the boss, without any player interaction. I imagine Tiche will probably get some kind of nerf in the future as well, if she is capable of taking down late game bosses without the player doing any damage at all.
