I was playing around a bit with Vuhdoo and am not quite that impressed. Firstly it takes ages to make it look like something I would use and secondly... it's a matter of taste if you like it or not, but I prefer my HoTs to be displayed with an icon, which makes the whole display slightly annoying as the contrast of timers/icon seems to be quite odd.
Personally, healbot is the better addon for my style of play. I have taken a little screenshot to show both in action (festergut 25h) and yes that was a kill and yes it was distracting to have two sets of frames open. I battle-ressed someone by mistake :/
The left hand side has my normal healing frames (healbot) and right there's VD with a few options turned on that I normally don't use (e.g. show incoming heals/overheal) as a druid. I might have to reconsider that for Cata but we will see. Apart from that there is also a heavy use of power auras (I love thee) and DXE. Now, while everyone seems to be focused on the visuals, I use power auras for one more thing:
Sound. It's just amazingly convenient to have a special sound for when a certain ability comes off cooldown - I use a spark/sound for Wild Growth, a few special sounds/visuals for certain buffs and debuffs in raids and my innervate cooldown, I get a clearcasting proc or gain haste, along with a spark/graphic in a place where I am likely to notice it without distracting from what is going on. This has helped me quite a bit.
The only mods I find essential are:
*DXE (or DBM)
*Healbot (I prefer VD on my shaman and grid on my pally)
*Power Auras
*Castbars
*Opie (unfortunately not shown here but it controls all my shifting with a mouse button and a slight hand movement)
The rest is a matter of style. Now, I have been playing a bit with
tukui , but it does seem to be a pain to configure - worse than VD - if you want to take the customisation a few steps further. For example, I like my chat text rather large, in a different font and coloured by channel and it requires to edit files to make it look like that. At least VD has an in game configuration.
But back to VD... does anyone have a few druid-ready skins for VD to share? I feel like trying something new and combining tukui with VD healing frames but I feel like I am in a dead end with my own customisation skills.
