I have been playing wow since WOTLK as a tank and now I want to get into raiding and as a tank I have a hard time getting into raids.
No guilds or pugs are looking for tanks and even LFR takes a while to find a group for while dungeons are instant.

The problem is that I want to get into dungeons instant, but I also want to get a good taste of what raiding is like so I want to get into pugs/guilds easy aswell.

would I be better off playing as a dps or healer or should I just stick to tanking?

(should be worth mentioning that I don't really care what role I do aslong as I get to do dungeons/raids)
(make the suggestion based on the role/class itself and don't take a players skills into account)
