I agree with OP. I really hope they either change or remove this GC restriction.

I am in a situation where a lot of my friends are spread out, it's also extremely unreasonable to ask them to swap over since they are ranks 35+. Basically the ideal choice would be all of us being able to play together.

I remember back in CT, my entire FC was pumped up about teaming up and doing it together. That idea got shot down quick, I'm starting to feel the same vibe with this GC restriction. Yoshi-P, please let me do frontlines with my friends. Thanks.
