Bold face if you just want to get right to it. *Edit for better wording*
Lightwell is one of the best heals in the game in theory but unfortunately, no one ever really uses it. Maybe because it's so inconvenient to click it and then to go back to doing your previous job. And in raids, people only think about using it when their healers are dead. It's a great heal but highly inconvenient. If your healers are alive, DPS and Tanks and even other healers have no need for using it as you should be getting heals anyway. In addition, getting healed by the lightwell takes away your current target, adding to the inconvenience. In PvP, outside of wintergrasp to heal other people not in your raid group, it's not very good as it has a tiny health pool and even in pvp, you're more occupied with killing your targets and CCing what you can.
The only time lightwell seems to be beneficial is when you're silenced or in duels. And getting silenced pve is generally avoidable and any type of silence isn't the doom of you. Anub'Rekhan, the silence is avoidable and even if you do get silenced, just calling it out allows the other healers to pick up your slack should you fall.
So how about a change in lightwell to make it less inconvenient. How about giving it a brain or a smart heal. Or Something to change how it works because they way it's working now, no one uses it. 3 min at a time it stays there and you're lucky if someone uses it once in that time (and generally it's me if I'm too lazy to binding heal).
We need a change in lightwell. How about making it a passive healer. For example, Cast a lightwell which lasts for 3 minutes. If a target gets below X% (like 50%) within the radius of the lightwell by X (EG. 30) yards, it automatically applies the lightwell renew to them and removes 1 charge, last 10 charges. Or something like that. That sounds like something unique and useful which and convenient for all people getting hit in raid.
/discuss, like it yes no? any other ideas?
Any other ideas I'm open to suggestions because right now I'm using Lightwell as a marker for where to stand to not get hit by flame wall. A job easily replaced by a smoke flare.
*Edit 3/17* Something no one has mentioned. There will have to be some kind of cooldown the lightwell itself will need have because it could just use all 10 charges at once on 10 different raid members, for example during a decimate from gluth. That pretty much means 10 heals healing for 4K every 2 sec for 6 sec. A little OP as a raid recovery and too much like old school Divine Hymn, but better.
*Edit 3/17 again* In addition, during what can be described only as a cluster uh.... idk about monitors so I won't say it but you know what I mean, 25 people in 1 area + all the trash or other mobs means lightwell's effective healing is gone because it becomes unclickable. If there was a like my bold text above, it would be able to heal people w/o the problem of clickability.
