Yeah I think its pretty stupid that they have a limit, I literally have 4 gamertags at 90+ two of them are silver a d I,just use them to invite friends and two are gold,and I actively power level and boost in Halo 4 and Halo 3. Its easy for me to get 100 friends in two or three days on Xbox with all the competitive customs and power leveling in MM on Halo 4. I need to clear out my FL though since alot of people moved to different game I think I should only have about 200 total but I just,cleared my main account and added about 15 new people first day CSR came out in H4.
