Serious Questions about UI changesFollow

I have some serious questions about the UI changes in the upcoming patch. I know things like decursive is gone and that's fine. My question is more about targetting and viewing stuff. From what I have been understanding, the tank boxes, which are part of ctraid, will no longer work in any form when in combat. Is this true? Is there no new way to change targets and have that info show up in this type of environment. If this is so then it will be a huge blow to a lot of guilds at first. Just trying to know ahead of time. Also, will buffing mods that auto target certain people be gone as well? Example, as a pally I use pally power and simple click on a class to buff an entire group. I can assign the buff through an interface. It will then randomly select a target from that class that is within range and cast the buff. Thanks for the info. Just not looking forward to revamping my UI 100% yet again.

Some buff mods might work when OUT OF COMBAT.

The general rule of thumb is any mod that chooses what spell to cast(including rank) and who to target, while in combat, is being disabled.
