I did not wait for specific subclasses. But for certain class skills that I can add to other characters with the coammand console. Unfortunately I noticed that the Arcane Shots as well as the Boots of the Giant kick are not animated and the respective skills appear with a time delay similar to the unique (elemental) monk skills. I find this incredibly unfortunate, as you are forced to waste up to 3+ class levels for the skills to work smoothly. I don't understand why adding (via the command console) certain skills etc. pp. e.g. of (sub)classes like the sword bards works, but not of certain classes, especially from the monk (Water Whip) and apparently all new subclasses.
PS. I don't blame Larian for it. I am just confused about it and want to express my disappointment.
