I have a suggestion: Consolidate your suggestions in one thread, and LURK MOAR.
Because there is no AT in game right now that has a primary melee and a secondary ranged attack set.
Play a Fire/Energy Blaster.
Energy Manipulation has a number of powerful punch attacks that could easily be passed of as Superstrength, one of which hurls the target a distance of 20 feet or so, the others all stun the target with a big satisfying "BA_DUMP!" noise.
Your fists glow when using them - pass that off as a fiery effect.
The problem is that with some combinations, as you must have seen in the Mission Architect missions, they're WAY over powered, and with the potential to be completely gimped too.
The game is balanced very well right now. Think about how many people play with very, very different expectations than yourself - how would this affect the rest of the players who didn't want to become supermagetankman?
Please read my FEAR/Portal/HalfLife Fan Fiction!

I have a suggestion. I see every time that I pick an archetype there is only primary sets and secondary sets to choose from. Why can't we have all those powers in one set instead of having only two powers to choose from after you pick your archetype. The reason why I say this because I wanted my character to have super-strength and fire blasts but you can't do that and I'm pretty sure that there are a lot of people out there that play this game that feel the same way I do. I'm not saying you don't have a lot to choose from. I'm saying put all the powers in one set.
