I would love to read blogger's thoughts on who they like to have heal them. Would you prefer a Holy priest of a Disc priest? A Holy pally or a Resto druid. Shammy maybe?This depends on some things in my opinion. I don't think I really have a particular choice.
I find I'm not that aware of my healers anymore since my transition from tanking to DPS (as you know I played a druid tank in TBC). When I was tanking, I had a good idea of who was keeping me up. You know when there's a lifebloom rolling on you because of that constant green stream in scrolling combat text, and the bigger heals from the other classes stand out because of that.
As melee DPS much of the damage done to me can be avoided by paying attention. A heal will come sooner or later, but if I can help it I might not need one right away.
I guess I depend less on the healers as a DPS.
In five mans, you usually take one healer only. Here is where you will really feel if your healer is paying attention to you. It's very fun as a tank to chainpull and test yourself and the healer. However, I have found out that DPS casualties are sometimes a result of this hehe. In 25 mans there is usually a healer for 'raid healing', so you will probably get a heal thrown your way.
The particular boss fight is also an important factor: if a healer or two is enough to keep up the main tank, than the rest can concentrate more on keeping DPS alive.
From a tank point of view, if you group with your healers a lot you know what they are capable of healing you through (sometimes they can pull off amazing things) and they know what you can take if you have your cooldowns.
From a DPS point of view you can't really expect them to keep track of all your cooldowns (I very much doubt if a healer knows if I used CloS recently or not).
As a bear tank, if I would really have to choose a class to keep me up I would say paladins. It's kind of hard to explain why -it doesn't help that it's been a while since I've tanked- but I suppose in my opinion, the flash of light stream of heals fit the dodged/non-dodged style of incoming attacks for a bear.
As a DPS, I think it's really nice to have a tree druid on raid healing duty. A HoT feels very secure for some reason - like you are safe for the time being, as long as that HoT is rolling. The fact that they can also use Swiftmend to turn that HoT into an instant heal when needed just adds extra security.
Say what? Yes. A good tank should be able to safeguard the DPS from a lot of damage (think picking up adds quickly and such). With a bad tank your healers will have to work harder. With a good tank (and we have those, I hope you do too) you are safe to DPS to your hearth's content, and an occasional heal will keep you up.
Special mention: PvP
It's always awesome when a player decides to heal in PvP. Here, there is that tank-and-healer-like connection between you and your healer, because often, you are the one 'tanking' the opponent regardless of your class. This is also a nice opportunity to see how a healer performs under extreme pressure: bosses do not make intelligent decisions. A boss will never try to lock down a healer while luring the tank out of line of sight of that healer. A boss will not alternate an immunity CC (like cyclone) between you and your healer so you cannot be healed.
