I'd recommend you to ditch Decursive and go for GridAlert and just using the Grid auras to announce whether there's curse or poison on a fellow raid member. I used to use Decursive too but found that it wasnt necessary. GridAlert does the same announce (vocal, which makes me look for that debuff) and I made Grid to colour the background of player frame according the debuff (green for poisons, grey/purple for curses).

Dunno which setup you use for your keybindings but as a mouseover-macro-user, I set up my left and right mouse buttons for abolishing/decursing accordingly.

I'm not trying to tell you what to do but as I've had similar setup before and improved it, I just thought to give you a heads up about the possibilites of Grid and its sidekicks.. also I always enjoy checking how other people heal with Grid and try to learn/improve my own gameplay.

All in all your setup is quite similar to mine. I use same indicators (grouped differently though) for hot's. Also I use GridStatusControlPipes for routing LB duration to mana bar. It's quite handy to see the bar shorten when you dont have the time to check for every number thats flashing on your screen.

Also, I like the lower part of your UI. Is that your whole screen btw?

I think it's improved uppy - I was never fond of the dot timers. Having it all rendered inside raid frames is the way to go.

Still not a fan of your huge button bar at the bottom. For me, everything I do is hotkeyed so I have the entire button bar compressed into a tiny cube. I use a GCD and cooldown timer for the timers I need to watch. And you should be able to merge decursive with your raid frames (if you're only worried about stuff you can decurse/depoison).

I sincerely recommend vuhdo. It has a far lower learning curve than grid and is superb once you 'gridify' it via configuration. I can't recommend it enough.

I'm also not a huge fan of giant hp/mana bars. IMHO I need three things - colour indicator (black=empty, red=really low (10%), yellow=getting low (30%), blue = all good) and a percentage. Most times all I need to glance at is the colour. That can be rendered as a small square which is the direction I'm currently going with BubbleHUD. Two medium sized squares for HP/mana.

I still love that smoothing overlay you have for your info area and the glossy button facade look. I need to steal that from button facade and stick it in my addon. The prominent debuff area is also something I really like.

My biggest frustration with grid type raid frames is that as a healer, I'd prefer them to be more central but then it occludes my situational awareness too much. And if I shrink the icons too far, then it's too easy to reach the point where you have information loss - it's simply too dense to discern at a glance.
