If I know I can get any item at any point in time, especially by possibly doing an easier task later on, then I feel like I wasted my efforts early on. Why focus on doing something when I can go back and do it whenever I want years and years later?
@Merus - Exodus is a fine example of still being able to get previous drops from that event but people are suggesting every previous drop be added to long term play and I disagree with that. I think there should be limited time offerings because at the end of these day limited time offerings give people more incentive to pay and play UO at a certain time period. These things are like a badge of honor for those that earned the items in that time period of play (or bought them).
At the end of the day I don't feel the need to give to give everyone a trophy *shrug*
