Well, johngie, I had a thought a bit more drastic. Radec was never really a ranged character in Killzone. He was very up-close and personal. The only actual weapons he had were his kife, his teslite grenades, normal grenades,a pistol (which isn't in his moveset in this at all), and his LMG. Superbot essentially made him Killzone: The Character. I really think in a sequel or something similar, he should have something more up close and personal for his moveset, and even Sly's cloak, though maybe limited. Maybe we could get another Killzone character to balance it out, or just get a more tricky moveset for Radec in general. I dunno, just a thought on that regard.
Alright. I'll agree with you to an extent. He needs more up close options. I really really wish his ground neutral square actually DID something. You can't really combo with it, you can't do anything with it, it has ending lag and is punishable. It's an almost completely useless move. His up square should actually function as an uppercut, I feel. Instead of starting above his head, make a quick upward swipe motion in front of him so he can do something with it maybe. Neutral triangle and down triangle could just use a little... something, imo. His forward circle does cover him, but it doesn't cover him very well. His up circle isn't a fast anti-air, isn't very good at combos, and it doesn't hold people like it could or should. I get at most 3 hits out of it and almost no option of a follow-up. Just my personal views as to what's wrong with Radec.
His Neutral Triangle should work on slopes. That's just BS that he shoots into the ground when standing on an upward slope (e.g. in Sandover village)
