But sometime all your need/want is more damage and sometimes you need/want extra effect on the attack.
Sometimes you do want the condition or extra effect: specifically every time you don't want to deal extra damage. Extra damage is something you want every round.
This is problematic for an option that isn't usable at-will. There will be the constant temptation to get the extra damage right away and not wait for the rarer instances where you want the extra effect. That and the fact it's used before the roll means you might end up wasting one or more of your superiority dice, and won't have them when the opportunity to use an extra effect presents itself. It's rare to have maneuver not triggered on a hit for the very good reason that it's a limited resource power, as those should always have *some* effect (hence why cantrips do nothing on a miss, but spells of level 1 or higher typically deal half damage). .
There should be both options available.
Maneuvers are designed so that you get the extra damage and the effect explicitly so you don't have to choose. Because choosing is really a non-choice because damage always wins. The status effect is the trap choice.
It's "both options should be available" but the options are cake or death.
It's not broken or imbalanced per se, but it's simply not a well designed or thought out maneuver. After all, a "moar damage!" option is a really obvious idea for a power, so it's exclusion from the game is very purposeful and was done for a reason. Adding it back in should be done very carefully and with lots of thought.
That's my feedback, which was asked for by posting here.
However, if you really want a straight damage maneuver without conditions or saves, look at Precise Strike. It's usable pretty damn often and is not a guaranteed hit. But it's not every round, so there remains the opportunity to use other maneuvers. The damage is actually higher than just adding a second superiority die since it's changing 0 damage to actually dealing Weapon + Str damage on that attack.
And you're less likely to waste it since you know the d20 isn't coming up a "1".
