Tanks using their enmity combo while being OT

[Iagainsti]

I just rotate SE and SP combo back and forth when OTing.

A 40 potency loss every 2 rotations for a permanent 10% damage dealt reduction on the boss seems worth it for me. For the 6 GCDs, it'd be 1200 Potency vs 1240 potency, which is a little more then 3.3% damage loss. If you factor in that we'll get about one Fell Cleave per 6 GCD's, it'd be 1700 vs 1740 per 7 GCD's, or about a 2.5% damage loss. This is also ignoring Auto-Attacks, and other abilities.

2.5% damage loss in exchange for the MT not worrying about OT threat, and a permanent 10% damage reduction should be worth it for everyone.

While I do commend you for thinking of your party by doing this, SP really only needs to be applied prior to subsequent big hits, or "tank busters" what with the current ilvl>required ilvl for current content. Most healers will now be overhealing the whole fight and you'll be short on damage.

Food for thought.
