It's not wack-a-mole. Think of it as "tag"

First let me just get this out of the way. In my opinion, light well is not a wasted talent IF it's used correctly. So throughout my time as healer, I've spec'd it, other builds in TBC I chose not to. Now with the improvement on it, I've picked it up again. I've found that it creates a cheap "buy yourself time" healing source - especially if one is assigned to raid healing. (I tend to drop one next to casters and ranged dps.)

My pet peeve (and point), is that people don't seem to understand that one click will buff you with a powerful HoT and that there's not really a need to click 10 times thinking that each click will heal you. I can't tell you how many times I've dropped a LW for a raid/party only to have one person use the whole thing in 2 seconds.

I would argue that the best possible use of a LW is during repositioning when a raider runs by, clicks once for the HoT and keeps on running as if to say, "tag, you're it." We must rid our raiders of the "I have to click this until the cog icon goes away" mentality.

My guild respects the LW and knows how to use it - mainly because our healers communicate with the guild via our forums, but throw one down in a PUG and it's like digital crack.

Don't even get me started on people who click on it before the fight even starts.
