Healing is very easy, but I've never seen so many bad players as of late. The same goes for healers and dps. Tanks that never use their cds and do their single target rotation on full packs of mobs, healers that never dps and spam cure1/physick, and dps that straight up disengage and do nothing during mechanics, losing tens of seconds of uptime.
But I feel this is expected, as the good and engaged players have been on break for a while since we've been lacking hard content for months now. I expect that once 5.4 hits good players will be back.
Also because bozja is fairly recent you can see above average and good players grinding there (though many people are semi afk there).
