I have been leveling feral from 1-70... at 70 I found a guild that needed a resto druid, so I went full resto (61 point in resto)... but 61 points in resto makes soloing a pain due to the time taken to take anything down :)
I switched to restokin.. I'm having fun! :D I have no balance gear, so my healing kit (which has 1560 healing bonus) makes a not so bad starting kit with about 600dmg bonus! I will definitely build a balance kit.. and maybe respecc balance to see the whole potential of it! :D
I haven't tried healing an instance yet, they only group I could have found was a reg durnhold to let another healer get used to heal... and they already had a backup healer.. but so far, I cant really be killed by normal mobs =)
