summoner has always been incredibly weak in wolves den since the nerfs aimed at it over a year ago, war bard dragoon was always the most powerful burst comp and tanky black mages allowed for control and choke comps

white mages have generally always been the most powerful healers vs burst but the least consistent, astrologian in lvl 50 is incredibly powerful due to its shield spam but the loss of e4e was pretty large (retrogredation remains to be one of the most powerful healer pvp skills in my eyes, an aoe wither and an aoe esuna in a single skill is pretty crazy)

Machinists play like a more utility version of bard which will not be used to its full extent in solo queue mode, in team matches though between the eyes on a bind+fullswing is incredibly powerful, along with blanks knockback that bard doesnt have
