Incorrect on the 00R. It will still get hit by beam specials unless someone shoots at the 00R during that beam special which then allows you to quantize out of it... seriously pisses me off when it happens. As far as i'm aware same thing applies with range spec.
Items is correct throwing sp downs when it has skill 2... *quantiz*
Using funnels is good, but i tend to do 1 at a time which drains 00R spec bar, then i go in.. *boom* 00R in bits
Best way of killing that OP suit is to target it first, it is squishy without the skills
