I know it has a fast recharge.
I know it is affected by MoR.
I know it costs 5 energy; just like the inspiration magic interrupts.
I know it is fast casting attribute based.
What I don't know is why it has to suck. Yea maybe if it "returned" the energy back to the mesmer then it would be useful. I still don't see a whole lot of use of this spell though;
"I interrupted your flare!"~mesmer
"Ohh scarry I will just cast it again and you are down 5 energy."~ele
"...damn"~mesmer
I know flare isn't a viable skill; but lets take a look of many of the current "best" skills to use. All of them have fast cast times and fast recharges; obsidian flame, woh, blinding flash, lightning orb...all of these have fast recharges so energy return won't do jack squat.
Say best case scenario; you interrupt a lightning orb on a fast cast nuker with duel attunements. They lose 15 energy due to the cost of the spell; but you lose 5 to your cost, then they gain 5 from your interrupt.
Net:
You down 5
They are down 10
Thats best case; however...we could use our other "fast recharge all purpose interrupt" savage shot...
Net:
You down 5
They are down 15 and 80 damage to the face
Worst case scenario; you interrupt and they don't care. Far too numerous to count really. Monks will simply recast due to fast rc, necros will call it a draw (net energy loss of both players 5, but they have soul reaping as their primary), eles ...well they simply won't care.
Yea its not affected by MoR; but I don't see this skill being used by that build anyway. Savage still interrupts non-conditionally and all skills; no matter what. This only interrupts spells; interrupts only if they are casting a spell; and punishes you for doing so.
Some say it has uses in pve as enamies have limitless energy. I still stand by my saying of "block it or kill it" simply saying either powerblock it to stop it from casting at all; or kill it so it is no longer an issue. Personally I think killing it is the better of the two; but ohh well. In this case we compare the skill to powerspike, cry of frustration...which both cast this spell into the abyss in terms of pve use. Savage shot remains more powerful than this skill; as it can even be used as a spike skill regardless of interrupting at all.
I simply do not see a use for this skill...if it gave you back the energy for countering then it would be viable. I know I would use it; would even throw it into a couple of my builds. That or make it "useful"; give it a unconditional interrupt, and return the energy to the interrupter and interruptee...Yet as it stands now it only punishes the mesmer that carries the spell.

. If they made power return be more like this:
