Tofu, Could you share your stat progression, since getting 120 Dex would probably require to drop a lot of points for other stats at level 100.
Thanks
Something I feel I should add to this:
If you're gonna do a BB/IB build, I've found it VERY helpful to go 120 base dex, with temporal dex boots. That removes all of the fixed cast from Bowling Bash, which actually ends up making Bowling Bash alone better DPS than BB+IB, if you gear yourself properly (sword guardian twin edge).
26k-30k bowling bashes, without gods/mvps/temporal boot procs.
