Return of Reckoning

Is there any reason why tanks have to wait level 25 for this tactic?
It just increases aggro generated, I wouldn't see this change a game breaking, right?

IIRC it was tied into when the first proper dungeon (Gunbad) could be run on live. All careers got their aggro tactics at rank 25 as they could start doing Gunbad in their mid-20s. I can't remember how challenging the city dungeons were.

They moved several low level abilities around for tanks recently. I'm not sure why they missed this one as it's pretty fundamental to playing that role in PvE.

I hope they move the menace to level 10 -- definitely would help with PvE for the lowbie tanks
