So I'm starting up full time raiding again, and my GM is convinced that disc is the worst healing spec because shield spamming isn't viable anymore. So I head over to world of logs, to prove to him that after the buffs, disc is much better than it was. In looking over the logs, I find that most, if not all, the top 500 disc priests are shield spamming. Are we really back to being bubble bots again?
