How do my final class choices "play"?

Hi guys. Firstly, sorry if this seems blunt. I typed this out for 40 minutes, then going to preview that 5 second loading screen for the site wiped my box, I'm just guna quickly type it all back with the jist. Also, don't worry. I'm not asking "what's the best class/spec" but rather want more insight as to how my final choices function in their playstyle. Don't wanna repeat the long road to 60 only to think "not for me...".
Hunter - Auto attack, arcane shot and tranq when necessary. Make sure your pet is fed to 150% dmg and keep him alive.
Mage - Spam frostbolt and be the CC god you are if needed.
Druid - Healing touch the guys low on HP and HoT the less important guys.
Shaman - Cycle totems depending on situation. healers use healing wave ranks. Ele uses shocks and LBolt spam.
Priest - You have heals for every situation, from preventing to HoT's to big chunk heals. Go shadow if there are 3-4 warlocks in the raid.
Does this sound about right? I Like the sound of priest but would like shadow to be more than just buffing warlocks. Also, I believe as a priest I'll be HK bait while levelling. Druid tiers look sexy but I just dnno how they feel to play. Mage was my main TBC-Cata but I spent vanilla on a hunter 2 shotting them so I dnno where that leaves me.
Basically, I want something that's generally good all around. I love the sound of priest/druid for groups but am worried that without dual spec solo content will be literal hell as a healer. let me know what you think! Looking forward to joining the community.
