I can understand why you proposed a lot of the changes, and would be on board with most of them. I'm not so keen with removing combust.
I do like the 2 new skills, and basically I like the combos, basically in order to have a decent QOL and to remain mobile (i.e. avoid those horrid cast times) , just hit a very simple 1-2 combo which fits in very well with the current skills. even the names sound good!
