Dan,
We all would really like to have the option to buy half our total energy if possible ... I know it would be difficult to measure everyones energy to see what would be feasible. What a rank 20 has is a lot different than an rank 500 so I can imagine how hard it would be to figure that for everyone but ........ the problem is still there and we all really need it.
Most of the guys in my legion sit and wait for some npc's to die after they locked in on them hopefully getting them over that nest rank mark. I Know the Queen Sacs are supposed to help with that but ..... sometimes more is needed.
Quite a few of us like to go on npc kill runs and sometimes we have to stop after we're all buffed with artifacts and it's a complete waste ... If this problem could be figured out it would be a win win for all of us ...
