k/p can be an okay healer. I don't think you'll find it fun, but is effective due to the ability to boost party member's damage (something highly desired in instances).
You have mentioned various classes before in other threads. I suggest you stop asking if the new toons you made are viable, and actually focus only on one (many responses have been made indication which you should focus on).
If you wish to get into instances the fastest, for the cheapest gold investment, buff classes, tanks, or healers re the way to go. And they aren't just zero damage classes. Mage/warlocks, well geared, can do 30-100m damage (bosses have ~400m hp) I have been told. 30m damage while increasing the damage output of all other players by roughly 50%. Not only do you get invites to raids, not only are you a much valued class to the raid, but you also deal damage worth noticing.
Healer equipment requirements are significantly lower than that of dps. Most players are still using lvl 80-85 equipment on healers. Learning to play them (learning to use healing addons like grid clique it) takes some practice though.
Tanks don't "need" amazing gear, but having it cetainly makes things easier. Plus you get a lot of responsability, and it takes a whiel to adjust to tanking if you've never done it before.
If you want an invite to a raid as an actual dps, hoping to contribute your fair share.....you probably won't make it any time soon. There are enough players active right now to fill all the damage slots. When forming raids, the roles we look for are never damage dealers. You have to compete with players who have the siege war title for Ironblood Will (+20% dmg for 15seconds), players with more tp than you, players with better gear than you, players with far more experience than you....You won't get an invite until you're at least as good as the other players in the pool, and that will take a really, really long time on new characters.
Or you could just roll a wl/m, with a warrior or rogue 3rd class, and run instances within a week or two, with the goal being to transition from support class to dps.
