Question/Concern regarding the Cross Role System...

[Driavna]

I think some people here are just "lazy", WoW did something similar and you can have a "good enough build" for everything or change according to the encounter (and in order to change skill in a dungeon at WoW you needed an item there. Here is not a problem. Just a few clics). Would even better if those skills change how you play your class (and even what stats are better for you) like Legion did with Shadow Priest ^^

Aside from Rescue I think I already have the equivalent skill for all of the healer role actions on my hotbar.

If they were adding 10 brand new skills and letting me pick 5 that might feel like customization, but taking 9 skills I can already have all at once and making me pick 5 is not customization, it's limitation.

Based on what I read you will complain too, your problem is that you don't want to rearrange your hotbar if needed.
