I'd go with Lower Resist. If you are running a one point summons tree, one point curse tree, and fully synergized Poison Maelstrom you'll get more bang for your buck out of the increase to Lower Resist. Golems are very weak until you fully synergize and buff them with lots of points invested into masteries. The skellies are more useful at low levels now. When I fight Mappo with my PM Necro for example, my golem dies in one hit. The skellies last longer individualy and also have greater numbers making them my main meat shields.
