I may have already said this, but I think it was on rpg.net...so hopefully I am not repeating myself. Game systems can be divided in several ways, and one of those ways is commonly "Permissive", and "Non permissive". So what does that mean? I'll use a couple of examples, D&D is a non permissive rule set, that means that the answer to "can I do this" is no, unless a rule says otherwise. Champions is/was a permissive rule set, the answer is supposed to default to "Sure, why not?" unless a rule says you can not.
So I've been playing Champs since it came out, so thats a lot of rule sets, and rulings to plow through. But I was amazed when 5 "allowed" you to multi attack, and people were not sure if that was good, when you always could. And I had seen it used all the time. It's a permissive rule set, so is there a rule that says you can't? If not "sure, why not?".
The answer to almost any question about capability should be "You're a freaking Super hero! Of course you can do that" My take on 5th and 6th is that it is written from a non permissive mind set, it often goes on to tell you the "right" way to build a power, and marks all other ways as "wrong". That is not the Hero way...IMHO...Lol
