I personally a believer that 100% or reroll is just going to exhaust you before you even play the game.
With that said, while its somewhat true that it's harder to get a random stranger with 100% to add you when you are 100%-less. There are many people with 100% that will add you when you are 100%-less. If you know where to find these guys, it's not hard getting those guys to add and keep you in their list as long you dont go inactive for a long period of time or do stupid things (e.g. sharing their rags to public).
