Well, for example pyromancer has great fire RR access(CoF+Thermite mines) but it doesnt make him particulary new player friendly. So its not that easy also. Though yeah, checking if combo provide some rr for main damage type is also good, though in my experience rr is less useful on normal then on highter difficulty
That’s true to certain degree, but not neccesarily.
Some class combo can be strong due to certain items/sets designed to overcome their lack of synergy.
For me, Soldier is most newbie-friendly because its builds dont rely much on specific items, and is good even without them. Take Forcewave, for example. It’s a SPELL with decent range, damage and AoE, yet it has high %WD and can leech HP, and it has very low energy cost.
Then, compare it to AAR, for example. Ridiculous energy cost, cant leech without specific item… or CT… also very high cost and much lower %WD to use LL.
