i have the game since thursday, i know
the normal klassic towers are fine difficulty wise, problem is you can only earn augments, consumables and koins there. no skins, no gear, no intros or winning poses and stuff.
so yeah, if someone cares about customization you have to play towers of time and get your head bashed in or getting annoyed by unfair modifiers which only apply to the player character and not the AI.
not to mention the fact that the towers of time should be the long lasting single player content because of the modifiers which keep the whole thing different and fresh. this should be a fun mode, not an overtuned grindfest which disrespects the players time.
i´ve played the Multiverse in IJ2 for months, i am done with the towers of time in this state, played maybe 25 of them and it is not good at all.
