All those sequences you can’t skip are incredibly annoying.

It might look cool the first time when the monster descends into the abyss (well of souls), but it takes forever before you can continue.
The same goes for Abyssal Depths. Why do you have to add a 5-second delay before you can move your character again? It’s really frustrating.
And the same with the Trial of Chaos—why would you do that? It just keeps repeating. Please add an option to skip these sequences (or remove it completely); it’s unbelievably annoying!

They do seem to have a talent for creating annoying things, don't they...

The anwser is easy.

To create a timesink, the longer you stay in the game, the more likely it will be that you buy some shit in the MTX store.

That is the only reason.
