Current State of End-Game Contents - A Blog Post from A Japanese Player

One solution could be AI-driven fights instead of scripted. An enemy that wants to target healers/top dps more often, ignoring the tank. An enemy that when for example blm starts slow-casting long skill, he instantly puts a heavy hitting aoe under him. Or enemy that uses some standard pvp strategies against players like cc'ing healers.

It would be fun to have maybe a couple of fights like that where its really difficult to get moves done because the boss is "smart". No enrage. Just really tough because the boss is reactive and pushing melee away and interrupting casters. But having the whole game like that would be even more annoying than what it is currently I think.
