After getting Summoner to 70, something just feels wrong with Aetherflow and Dreadwyrm sharing the same bar for me. Dreadwyrm becomes something that I have to burn immediately when it comes up because of how slow it is. On top of that, if I don't, there's some skills I cannot use because they require Aetherflow stacks and I can't use Aetherflow if Dreadwyrm is up.
