Remember Phreaks comment after the MSI Show Match?
"I just wasnt used to playing on 4 ping."
Living also in Fl and having to dael with around 110 ping on a daily basis is playable, i know others over in Washington state and in Cali who run on 23 ping which would be nice too. When i get ping going over 200 i notice the difference just like someone who plays with a 20-50 ping would notice the change playing on something around 100.
I do remember a guy in the forums once said in a thread about pings
"I play with 10 ping constantly and decided to make an account on EUW, well playing over there i had around 160 ping which wasnt bad, it was playable but not too terribly hard."
Well as has been said so may times before and back then we used to get a standard 160 ping on the east coast it is what we play with and get used to. It really depends on who your ISP is and where you are located that will determine your ping and then how you actually deal with it.
I know if i got a ping under 50 i would notice it and would it help me play better? maybe but i still do ok with my 110 ping even against guys with <50 ping.
