My thoughts so far:
- The only incentive to use stardust is to make your pokemon stronger so you can attack gyms
- But attacking gyms is bugged most of the time where it freezes up or the enemy gets stuck at 1hp
- Because of that, I've saved up all my stardust (98k) until they fix the bug or I find something like a Dragonite/Snorlax/Aerodactyl
- The higher level you are, the higher CP pokemon you will run into, which will make your older pokemon obsolete and your stardust wasted
- I'm level 19 and everything I have is exactly the same CP I caught it at, except for the Jolteon(which I evolved)
- fukk Pinsir. I always run into them with extremely high CP but their damage sucks. My 800+ Pinsir got washed by a 500+ Electabuzz one on one
