I would support the idea of grenades having a timer. That sounds like a really fun and not all that hard to implement mechanic.
Anyway for people complaining that certain things are OP, I haveto ask: Did you complete the game in honor mode? If you did then I'd say its fair to ask for more challenge (even if I think removing features is a terrible way to go about creating more challenge).
But if you did not complete the game in honor mode, then how can you really argue the game is too easy?
(also did you try simply playing it another way? after my first playthrough I decided to skip all the ranger stuff because it was so packed with stupid one shot skills.)
