When playing Kineticist it feels most of the time that it's missing something or that I would love to get some of their powers as Tech Specialist
It makes me wish that levels went up to 20 but not having 8/16 more abilities and perks, and instead upon reaching level 13, you were given a choice between getting the other first 8 special abilities of your current job or becoming 'multi-class', and choosing from the first 8 abilities of a second job (of course not getting their 12 perks from leveling nor their starting ability)
That way you could choose between going all-in with your current job or creating 'hybrid' jobs, something like the Infiltrator, Sentinel, and Vanguard from Mass Effect
