Oh no, how dare SE not write "after using melee combo" for people to realize that a non-combo weaponskill should not be used?
100 potency vs 470, even Enchanted Riposte is 210 potency so WHY would you even use Enchanted Redoublement without comboing it?
And yes, god forbid you're punished for bad play!

The tool tip is the least of your worries, mate.
Just place the buttons next to each other and build some muscle memory so you don't mess up the oh so confusing 1-2-3 rotation that is RDM melee.
