There are some discussions on the main forums but I'd like some advice from a priests perspective. My situation is that I played an Alliance priest to 60 and did some raiding pre-burning crusades and then dropped out. So all my skills are rusty and I want to be a more casual player. So a friends description of the dungeon finder and the heroic level instances somehow gave me the idea that it might be possible that 5 manning with pugs might let you get a decently equipped character over time without adhering to a top guilds raid schedule. Please don't disabuse me of this notion in your responses. I want to be the best casual player I can be.
So I read the excellent "Ultimate all you need to know" guide and created a discipline horde priest and I've been poking along to level 22 without doing any real prep work just playing the game with dungeon finder. Now though I think I need to do a little homework and prepare a bit more. In Mozareds guide he touched on macros and mods but didn't go into a lot of detail. Is there a new standard out there now that I might as well get used to just in case i later on decide to raid? Four years ago I think everybody used CT Raid assist, is that still a "standard" and if you use raid assist to you also use an addon like Healbot, Grid or Pitbull? Also is there a discussion or a favorite web site on what macros everybody likes to use? I'd really like to be an efficient, competent healer so that when paired with a decent tank (and 3 monkeys for damage dealing) theres a chance of feeling the satisfaction of good teamwork and a well won victory.
