- Have some sort of indicator that an ally is revived. For instance colour them slightly different if they are revived but still down or perhaps keep the heart revive icon above the character. Why? Because sometimes I rely on the revival invincibility but when I get there and realize they've already been revived it is usually shortly followed by taking a skull-full of damage.

- Have a way for the party leader to indicate mobs with targets/icons. For instance holding shift while left clicking on an enemy would put a diamond above their head or something. Though the hotkey or what-not could easily just be set by the players.

- Have a way to program your own macros. So far the only pre-defined macros that I commonly use are the Fall back and Attack keys. There are quite a few things that I'd like to be able to say in certain areas (most commonly before fighting Vanaduke) and having to type it out each time is rather annoying.
