Yeah, I’ve built up similar speeds. I don’t see a problem with it, considering the amount of sacrifices you make to reach those speeds. You can’t use that build in high level GRs.
I wasn’t aware that GR150 was the cap, but still, insane movement speed builds wouldn’t be capable of killing anything at that GR level, so I don’t see a problem with it. I don’t see a max movement speed build like that working well enough to take advantage of the speed by flying through rooms and killing everything as you go, on anything past GR100. If you have to do loops around an elite pack to kill it, then the speed isn’t being taken advantage of.
I think the amount of movement speed gained from sets like the GoD is obscene. But +12% movement speed from Lacuni Prowlers isn’t what caused the problem.
In my opinion, no set should give more than +60% speed on its own and still keep damage and defense up to par. +160% is mad. I think removing the cap and dropping set speed bonuses down to more reasonable levels so that a cap isn’t needed would be better. Caps cause stats to go to waste. They cause the already-inflated bonuses to become the ONLY bonuses, while the small bonuses that weren’t really the problem in the first place get cut off to solve the problem created elsewhere.
If the cap was removed, I doubt you’d see people using it to get top rank on the leaderboard. The +12 movement speed on things like amulets and bracers would be giving up vital bonuses.
