"except corrosive projection only works on grineer and bosses since they're the only ones with armor, and energy is siphon is so slow you might as well not even bother. "

You can use shield disrupion versus Corpus instead. As for energy syphon it's not slow at all. Also with recent buff to rejuvenation it became a viable aura. A little more then 10% damage increase to a level 1 enemy is really almost nothing.
