The only one i wouldnt go with is red mags. Yes he is helpful, but his primary advantage comes against metal and especially robots, which he does well enough as a 5 65. Will def r4 mine one day, but not as a first. Nf if awakened is probs your best bet. Dont know much about rintrah though, dont know if he is the most viable for act 7 and 8 but ive heard that he is extremely fun. Neutralize is also amazing, and his root mechanic is pretty awesome. Warlock if you are lacking on utility champs.
