My list of things I want is pretty short these days because the more I gear, the more I realize where my limitations actually are.
You can cap cure potency without using either your main hand or offhand. Translation: no staff required and no losing TP for cures.
Enfeebles apparently aren't getting fixed after all, so what else is new. I think we all saw that coming.
If you've kept up with Stoneskin, enhancing gear, fast cast, and PDT, you're probably as tough as me. Which is pretty obnoxious. Phallanx getting a little love would be appreciated, but not a lot, just a little more scaling to level 99.
Nuking is looking kinda shitty at level 99 and so are Enspells. Spikes aren't even worth mentioning unless you are talking about a major overhaul. This is essentially our sore spot now. If you kill 2 birds with 1 stone then you release Enspells that give us affinity and actually hit for more than Enspell 1s. You will make a great many RDMs happy by doing such a thing.
Occult Acumen. Gimme. No seriously. Do it. That's the only job trait I care about.
