Feature list was what I was waiting to post. Even as I wrote that first post I was thinking of why they really "needed" ct raid. I'll get back to you :) Off the top of my head, I know they obsess over "ready checks" and commanders being able to put HUD text in middle of screen for directions.
As a healer I like the ressurection monitor. I'd like to see that expanded. I'd like to be able to see: Whose rez is in cooldown (druids), whose soulstone is in cooldown, who is soulstoned. As much comprehensive rez organization as possible. I've been told to battle rez someone before... and if they're soulstoned, they dont need mine. And indeed if I do cast battle rez while theyre soulstoned, the soulstone takes precedence. So they use the stone. but it still eats my rez cooldown too. That's crappy :)
I'd also like some kind of healing organization. I'm not going to cast Healing touch if a priest is healing someone (unless theyre taking big ass damage).
Maybe tracking how much incoming damage people are taking, estimated. Like, MT1 is taking ~500DPS, estimated time to live: 3 seconds. Triage help to know when there's nothing you can do to stave off damage on them, or get a big heal off quick enough, and just let them die and go on to the next one and save that 2 seconds of the 3.5 second cast that would have been wasted as they died.
In an ideal world, I'd go for an Ace raid assist. But getting all our raiders to use RaidAssist was bad enough, without confusing them further by changing it :p Some of the guys I had to step through even the part of mod installation involving Windows Explorer. The pessimist in me (which kicks optimism's ass on a daily basis) says this would never really catch on wide scale.
