Playing as an enhancer works quite well.There is one drawback:
Maelstrom Weapon Buff stack up to 5 stacks. Normally you use the buff only if you have 5 stacks because certain casts are instants.

[ 53817] = {403, 421, 8004, 73920, }, -- Maelstrom Weapon => Lightning, Chain Lighting, Healing Surge, Healing Rain (Enhancement)

Unfortunatly the spells above start flashing from the first stack on. This means they are always flashing because you always have 1 onre more stacks during a fight. Could this be changed to flash only if you have 5 stacks as ist was in Inline Aura?

How does the default UI behave when AdiButtonAuras is disabled ?

Ok I found out, that I can disable the flashing in the config if I click on the spell.
The normal behaviour is, that with 5 stacks you have a visual effect around your character.

For me this is solved. Maybe this should be the default.
