When do you think this will arrive?
What do you think of this system?
Do you think it will break the game?
What effect will it have?
My personal opinion:
I think it will come before the end of the year.
I believe it is vital that it works for all players. Rural players with no Pokestops should be able to request one, but people have to care about the game to be able to request. I think it could be a yearly request if you are below level 10, when you hit level 20 it gets lowered to 6 monthly, then level 25 lowers it to 4 monthly, then 30 goes to every 3 months and 35 lowers it to monthly. Level 40 get it weekly.
It won’t break the game.
It will help the rural - urban balance and would allow people to request people to request pokestops in locations where they feel a missed oppertunity for a pokestop has taken place (my town’s biggest park is one of only 2 in the whole town to not have a pokestop)
