Another Sentinel idea

[Wavicle]

This is an idea that would work together with whatever other changes might be made to Opportunity, including making Opportunity ONE buff instead of two.

What if...Opportunity was set off by a separate inherent click so that you weren't forced to use your attacks at a particular time, BUT, here's the key part:

 

that click could be set off DURING other powers animations.

 

This way you can get your debuff up when you want it on whatever target you want it, no matter what else is going on a that moment.
