I used to play summoner in Heavensward, on my old account. When I learned that the summoner lost the pets (they're not pets anymore now, just funky graphical effects for DOTs), I didn't even unlock SMN. Found SCH boring enough as is now, that the faeries are just cosmetic perma-HOTs, ARC is completely ruined IMHO.

Here's hoping that they'll one day introduce something like necro, with actual pets.
