Hi Ahglock,
If you want, I'm sure someone here can rewrite the flavor text for Torturous Strike and Positioning Strike so they're more "cool" and "un-lame" for you. I already rewrote Torturous Strike as a dueling swiftblade technique called Penetrating Strike in an earlier post, but I'm not very good at that sort of stuff.
I mean, because its obvious you're just having issues with the fluff. Instantly dealing double damage with a single attack (plus an ability score bonus if you take the right "talent") or doing normal damage and slinging your target around (which can be up to 4 squares away if you take the right "talent") are both pretty impressive at 1st level. They're certainly the equal of most (if not all) 1st level encounter powers from, say, Tome of Battle.
And, you still never addressed my other query. What stops your players from using their "strongest" or "best" powers as often as they can every single fight?? They have no incentive not to, especially if they roleplay their best power as their "favorite" or "signature" attack. I mean, other than DM fiat, that is.
Laterz.
