Summoner skills have not changed since 1.10 except for blood golem. Norm Duriel was usually the closest battle I had...Iron maiden and clay golem for the win:). I suggest more points into mastery early, vs summon skele...otherwise norm diablo can be somewhat problematic.
You be able to get through hell without too much of an issue,but it will slow quite a bit if you lack any gear. It is extremely safe compared to a lot of other early ladder-season builds.
shop for wands in act2 hell if you haven't found weapon of worth.
