Yeah, I seriously don't understand the medal dilution. If you hand out a medal for every little thing, it stops making them special and interesting - it defeats the whole purpose.
I don't understand why there aren't dedicated no-scope and quick-scope medals for the sniper rifles (things people have been requesting), but there's a medal for tons of little stuff no one cares about. I also don't understand why they redefined the medals in Halo 3 and onward, either.
A running riot is ten kills in a row, and four kills at once is a killtacular, dammit. Why did kill frenzy have to be changed from "at once" medal to a streak medal?
Boggles the mind.
Gamers like progress and rewards no matter how meaningless it actually is. Carrot on stick and little treats makes everyone a winner no matter what level.
