I can say something about pros and cons regarding each build, from my understanding, regarding “easy to play”
Warder +: few buttons, you can even remove blitz if you think one movement skill is enough
Vindicator +: have passive RR thanks to aura of censure.
-: you have to reapply word of renewal and you have to cast inq seal and make sure you stand on it (you need to do that with wendigo totem anyway so perhaps this is just a minor thing)
Druid: + : also few buttons. One button you need to time well and that is mirror of erectoes.
Elementalist: - :you need to cast mines to get RR
+: panic “button” is a passive in blast shield
Conjurer: -: you need to reapply blood of dreeg and cast your RR skill curse of frailty
