Because, in fact you choose what power you are trying to use. I mean are you saying that when trained warriors fight they throw all kinds of wild attacks until one succeeds? And this reasoning still doesn't explain why a Rogue who sneaks into a room full of enemies clustered around a table, hides in the shadows and takes perfect aim, cannot succeed at Blinding Barrage.
Hmmm...the rules?
In previous editions, if you tried to do a maneuver all of the time, it went like:
Rd1
Me: I try to trip my foe.
DM: You fail.
Rd2
Me: I try to trip my foe.
DM: You fail.
RdX+100
Me: I try to trip my foe.
DM: You succeed.
I can try all day, even if I only succeed once.
In 4Ed, once daily maneuvers can only be tried once per day, successful or not. The choice is taken from you.
These are not equivalent designs.
The Player chooses what power to use. The character doesn't stand there and think, "Well, what power should I throw at these guys...hmmm. Well, that's a Daily, better hold onto that. Eh, I'll just smack 'em with an at-will, good enough. 'KAY STAND STILL GUYS, I'M SMACKING YA WITH MY AT-WILL!"
And I'm not saying they keep actually attempting to do it, but try and find an opening for it, maybe actually attempt in it once in a while.
Every watched a movie where two guys are sword fighting and one pulls off an awesome move? Did you ever wonder why he doesn't just continuously do that?
Incorrect, thanks to the Reliable keyword, which I've only seen on physical attacks so far.In 4Ed, once daily maneuvers can only be tried once per day, successful or not. The choice is taken from you.
Yeah, but were talking new opponents and optimal conditions...for Blinding Barrage...yet it auto-fails. If they line up along a wall 10 ft away, don't move or try to defend themselves, guess what, it's still an auto-fail if you used it earlier that day. It doesn't make sense.
I'd rule that no, it's not. If this is the case, it's no longer an encounter. A rogue can Blinding Barrage that rock over there as much as he wants...until the rock gets up and actively tries to beat on him.
That's a house rule though... I mean I can houserule there's a recharge on them, but that's not what were discussing... as written BB works like that.
