Nope, there is no awards/rewards reduction after X number of hours playing, unless you are refering to needing more xp per level at the higher levels (and facing tougher foes after lvl 40-ish). The only way CoH discourages "powerleveling" is by having plenty of low/mid game content and a relatively easy to reach lvl 50 security level cap (the cap was lvl 40 at release). Although I myself don't have one (I have shown a strong tendancy try a different archtype by level 30), I do know several people who have managed to get 2 or more lvl 50 "toons" without quitting their job/social life.

You may be thinking of World of Warcraft, as they were attempting to implement something like that.
