Um, I don't mind the occasional dips, but when there are 2-3 wizards in the party and each of them starts using the storm skill/lightning rod's attacks etc. at once, fps really go down.It's really not that bad, yeah. I'm shocked to see people acting like it's a severe issue or a deal-breaker, even factoring in the hyper-sensitivity of the core crowd.
Honestly, I would be surprised if it didn't given the amount of effects on screen.
In other news, prices on Amazon.jp are hilarious.
