Just wait 'till SO's, it's an AoE control so it has a lower ACC than most powers.
Don't forget it only affects minions as well, Lieuts & Bosses won't be stunned. So some of those "misses" could just be unaffected.
Personally I think its a useless power for the most part.
It's not your imagination, thunder clap is pretty much pants. Even fully slotted with SOs it's not impressive. I dont see why it can't at least have a higher inherant acc as it will only stun minions anyway. Still, i'd give it a try anyway, you might like it, different strokes and all that.

I want him at the shrinking of the tide;
The old snows melt from every mountain-side,
And last year's leaves are smoke in every lane;
But last year's bitter loving must remain

It might miss but it looks pretty, right? 
In all seriousness... SOs do improve this power a fair amount. However, carni is right it only effects minions unless you have a power in your secondary to stack it with (or unless you are teamed with someone who can provide a stacking power).
bah, will spec it ouy tonight, the realy annoying thing is that i respeced it in, the even more annoying thing im gunna respec back to my old spec b4 for the respec (keep up!!) ahhhhhhhh 
DAM FREE RESPECS + BEER *sobs*

Yeah, but the Def based toons got annoyed. Especially the Stalkers being auto-knocked out of hide.

..it only works on minions?...lol...
what's the gain with that? i think it's the only power in the whole game (coh and cov) that only works on minions..
Why that? O_o why doenst work hoe other powers and doents stun lieutenunts too, and bosses with 2-3 hits?
It's defender for a start...
Oppressive gloom, choking cloud... there's quite a few powers with a mag at minion level. They affect Lt's and bosses, but do not have a high enough mag to overcome their mez protection by themselves.

[/ QUOTE ]Most AoE controls (Discounting soft controls) outside controller/dominator sets only affect minions.
