Let me be clear, I use Lightwell. Yes, I do, I use it for myself. Only myself. I place it where I plan to be spending most of my time, or near where I'm going to be running. It means I'm able to set it up before the fight starts, so it's off cooldown early and I can use it again. It heals about 5k per tick, and means I can have myself topped up while whack-a-moling the raid, but I still think it could be better/changed.

ToC implementation was just an example of what could be done with the ability Lightwell, an example that it could be better, not that blizzard should make it that way exactly.

How many people have to NOT take Lightwell for it to become a "boring talent that no one likes?" Why is it that the elite of the elite never take Lightwell? Sure, it looks cool, it could have been a good idea with different combat mechanics that didn't require rotations, but in the end, it just doesn't work. Compare Lightwell with other tier 7 healing spells: Swiftmend, Mana Tide Totem, Holy Shock, even Power Infusion. Let's make Mana Tide Totem an on-click mana return... How many other spells do you need to raid warning or whisper your raid members "Oh, if you want mana click on this totem here"...

How many other spells in the entire game can you mention that involve player interaction such as this? A spell that for other players (those that must right-click) cannot be key-bound. Even other spells that require clicking on other players, e.g Tricks of the Trade, Misdirection, Intervene, can all be key-bound and clicked without switching targets, limiting down-time between their rotations and what-not.

Your dedication to writing this article is absolutely linked to your opinion on Lightwell, but not just Lightwell, all spells, broken or otherwise. You are entitled to your opinion of course, but I would think that writing for a website such as wow.com, the writer would have the player's best interests at heart. I do not believe this is the case as I believe player's best interests involves at least an attempt at changing Lightwell, instead of forcing all Holy Priests to take it. The comments towards the original article and the voting towards said comments are a testament to that.
