My main is my tank, not my healer. I have Pally, Magex2, Lock, Priest

And 5x renew would be great when I don't have PoH at this level when my group takes random splash damage and I just wanna keep moving. That isn't the only situation I would use it in, it is just an example. I actually have F1-F5 as specific party members right now, and often I'll bubble the whole team, then run in and AoE spam AE, with the lock doing Rain of Fire. Mobs die fast, but having that little edge in health is nice. I'd like to do it mid-battle as well, without having to reach up to all those keys - since I am busy with the AE etc.
