WP/SS IO sets

So I'm just now starting to get IO sets in my melee powers for my tank and while I'm a loooong way from being able to afford it I'm curious for anyone with loads of money... what power would you put the Hecatomb set in?

Knockout Blow. You want the recharge for that attack. It's a bit end heavy, but you probably have quick recovery and stamina.

However, this is the kind of question that does better in the specific AT forums, such as the Tanker Board (posting this in the defender board instead would be amusing).

On my Brute I put it in Punch, so that the proc would fire more often.

"It depends" - on your overall build, set bonuses, and general attack chain.

Slotting purple sets out to the attractive 5 slot set bonus isn't particularly better for individual power enhancement than non-purple sets due to the ED "soft" (in sarcasm quotes) caps. And since the purple sets have higher-damage, higher-chance procs in them, I think it's best to slot the purple set in a power you're going to fire often.

My usual advice is to skip the pure damage IO in favor of the proc, then use an IO from another set, or an HO, to "season to taste" with the 6th slot (if you're not sure what your taste is, the mako's bite quad covers all the bases for this in melee attacks). Double-proccing the attack with a non-purple proc is also viable, especially if end management isn't an issue for you.

On my WP/SS brute, I slotted Hecatomb in Haymaker - my overall recharge (90% bonus + hasten) is such that I rarely ever use Punch, favoring haymaker and my patron ST blast (mu lightning) over it in the gaps between KOBs, and using foot stomp even single target in the rare instances I find myself having to wait for an ST power to cycle. KOB itself is slotted with 5 crushing impacts (skipping the dam/end) and the 6th slot is a Force Feedback rech/end, since the 5 crushing impacts already provide ED-capped damage and 2 SO's worth of accuracy... not that accuracy is a problem for me considering that I get another 74% worth to my entire build as a set bonus, and then have Rage, frequently double-stacked, for a large tohit buff as well.
