I really haven't been in many fights that weren't grinds.
I think it's because none of the player's at wills seem tactically interesting. Pushes and slides, unless you are in the room of grinding gears, tend to not matter much. I suppose if every encounter ever had some kind of mechanically and tactically interesting situation, that would be a bit better, but it tends to come off as contrived, generally.
That, coupled with the default assumption that encounters miss a little under half the time, and you get people weefing with their cool effect and being forced to just spam correct tactical at will B. Is there something as a player I'm/we're doing wrong? Is there something I can poke the gm about? The whole party takes differently useful powers, generally speaking a damage at will and and utility one. (Like reaping strike/cleave or howling strike/pressing strike. The only use for positioning is to get a +2 to hit for essentially every character in any game I was in (nobody plays rogues....). The problem is that flanking works both ways and generally one or more enemies gets the same bonus to someone because you are out of formation.
