I like the idea of giving the combo system something extra, but just pumping out extra healing all the time seems kind of wasteful. As an alternative, maybe completing the combo could help charge the lily gauge faster. That way doing more damage helps you with your healing, which in turn helps you with your damage (via the blood lily).

Also, I’d disagree with making all of the damage spells take 1.5 seconds. I’d say leave glare as a full gcd, and shorten the other two. This means you have weave windows, but not an infinite amount of them, and it forces a decision point. When you get to the glare part of your rotation, you have to choose to finish it off with the big damage move, knowing that doing so will cut you off from healing and movement for a gcd.

Those are just some preliminary thoughts. I’m sure there are plenty of other things to say on the topic.
