OK, but then to be fair, please compare leveling up this new GB from 0-60 to leveling further another GB from 60+.
It's a fair point.
I still think the best move is to avoid it, overlevel your Traz/CF/Arc etc., and stay flexible with space. But if you're really at the end game with all GBs you want at 60+, the key ones at 100+, and you have nothing else to spend FP on... I guess this thing is about equivalent to a single A-tier event building. >_<
