New ways to control your character

[Chicktopus]

I don't know if this is a stupid idea or would even work (although I understand it's a massive undertaking), but what about ability combinations replacing some abilities, for example in lieu of the Assassin's Thrash ability, the equivalent would be attack->attack. Volatic slash, when taken as a talent would then be attack->attack->attack, in which the third would be the more powerful strike. Another example with the Sith Warrior's Vicious Slash, which would be triggered by holding down the attack button.

 

The advantages are that this would free up ability space and add extra ways in which o control your character.

 

Naturally the GCD would need to be replaced with some kind of weapon speed modifier. Thoughts?
