Using the mouse I can look and point behind me while running and cast LoD.
No, Actually, this has been in the back of my mind for a while, but I don't think the underlying framework is in the game to support it. League of Legends does this for cone-AoEs, and it's really quite fun. If it can be made to work, it has my full support. I suggest you go to the suggestions forum, or start a new thread here, about it, shipping the idea, if you're strongly after it.
I'm fine either way, I think both could be fun. :)
And actually, your ten man groups DOES have less health. Think about it this way: your ten man group has a combined HP pool of about 70,000 x 8 raiders, plus two tanks at 160k each (those might be horribly wrong numbers, but they're what comes to mind). A 25-man has three tanks, usually, at 160k, and then 70,000 x 22. If your LoD restores 5-9k health per target hit, 30-54k for six targets, which is a certain percentage...
You know, dangit, I am a distractable fool. I will come back and describe this in more detail later. For now, imagine this scenario in wrath- in a 25-man group, AoE pulsing aura fight, 25 people take that damage each tick. In a ten man, 10 people take that pulsing AoE damage. If, say, it wasn't pulsing aoE damage, but rather, like, Toravon's Ice Spheres, in a 25-man, you could expect 5-8 people to be standing in the area and scattering upon the orb's arrival as it travels. In a ten man, 2 people, perhaps three, would be taking that damage. In the ten man scenario, you hit the 3 people taking damage with LoD, perhaps missing the fourth nearby dude. In 25-man, you hit the 5-8 person area, and only the 6 most damage people get heals.
It's about proportions. I'm not certain of the math. I'm gonna do some analysis, but for now, I'ma post it and learn Ochem. :)
