I think class choice is a huge factor for this season. Healing on shaman has been fun, since you have all of the tools to deal with extra mechanics on top of having good healing. Resto druid has been a pain on the other hand.
They have some upcoming tuning that should make some of the BS mechanics less of an issue.
Sony needs to stop with these live service games. Nobody is interested in a new one. Everyone who wants to play one, already has their game chosen and do not move from it.
