It 's the Skillsystem (especially the Skillchaining) that needs to be a bit more optimized
for higher Pings and situations like these especially for an MMO (at which such Pings are often considered regular)
I'm playing on the EU Server and getting Pings between 150-250-300ms.
I'm Dual Wielding and Switching Weapons often and it 's especially noticable.
But I'm positive that these will get worked out - there are far more serious Problems right now - like the Teleport Hack. I've had someone porting in my Face - mining - and porting away before I realized what the **** was going on. It was so fast that I couldn't even take notice properly of his name.
