I level freeze a bunch so much so that im lvl 45 with 14.5k bp and still growing, I feel like level freezing is good if your just starting out and you wanna get pretty strong, but its mainly around your server its quite useless to level freeze on Kozo's server since he will always be ahead of you one huge benefit is sage world once you get in the proper bracket you get mad points and advanced refines for example I have 116 advanced refines but no use for them atm. Also it benefits Strong Approaching when you unlock it you can quickly speed run it with major ease. Personally I think you should go for level freezing only if you have enough patience to wait it out and wanna try hard through the game, if not and you just want to have fun don't level freeze
