Honestly I think that any skill with a decent cooldown (30 sec or more) that raids and raid leaders DEPEND ON for any given fight is worth listing. Lots of fights RELY on things like Shield Wall or Tranq Shot and others. Why wouldn't raid leaders want to have this information at the their fingertips? As for innervate and manatide, man... if a raid or heal leader doesn't care to see the cooldowns for those then I'm sorry but that person is just a straight up idiot who isn't taking advantage of tools in their raid properly. In many fights in late AQ and Naxx it is a requirement to get good innervate and manatide rotations going all the time. Knowing cooldowns for these things is supremely better than having someone in vent yell out asking "how much longer until mana tide!!?" etc.
Whether or not Shield Wall, Tranq, etc are desirable is irrelevant for this mod. The fact is, CTRaidAssist/oRA2 only support Rebirth, Ankh and SoulStone; anything beyond these is beyond the scope of this addon.
I'm not at all opposed to the idea of having extra cooldowns visible. But if you want to see them, it will be in a separate addon that *everyone* will have to install to make it work - and that's not what this addon will ever be.
If oRA2 decides to add support for extra cooldowns, then this addon will add them then. Petitioning in this thread to add support for cooldowns that there is no existing mechanism to keep track of will simply be ignored, because this is just meant to be a view for data, not a collector/broadcaster of cooldown data also.
And re: raid leaders NEEDING to know about innervate/manatide.... I'm a raid leader, and we're well into Naxx... I believe in NOT micromanaging my raid members; and personally, I've never told a druid to innervate, or a shaman to mana tide - and most of the time, our druids are pretty intelligent about battlerezzes before I even have to say anything - and they've all learnt to do it on their own initiative, or pre-arranged for fights as appropriate.
Then again, I think we're one of very very few guilds well into Naxx that doesn't use Vent/TS... so maybe we're just odd.
