Playing Eureka recently, I've noticed that it gets to be really straining on my hands/fingers trying to maintain the 2.5 GCD while grinding trash mobs for extended periods of time. I figured that this sort of problem could be mitigated somewhat by introducing an option to receive a buff that would double recast times, yet double the potency per action. The buff could be removed when entering an instanced piece of content, such as Baldesion Arsenal or whatnot, as I could see some unforseen balance problems cropping up like with snapshotted DoTs, or whatnot. But, it shouldn't be a problem for grinding overworld mobs; I'm not sure anyone would be too concerned for that. Plus, it would facillitate socialization during grinds, just like the game it's trying to emulate, by allowing more time to type between actions.
