What remedy would you take if you face latency and ping issue in any MMO games, eg Warcraft for instance.

Buy a better internet package or play on servers closer to my location.

So...none of the things you suggested.

wtffast works if you have bad routing, but it depends what the issue is

Switching from wifi to ethernet helps. Using a proxy will raise your ping in almost every instance...

at times even you have better internet package, you still get high ping because of distance issue.

agree to 2nd option though.

So you suggests getting A VPN (GPN according you WTFast) will do the job.

actually, i agree to you, and want to give some more insight. I used HMA, WTFast and PureVPN. PureVPN gave me a better response.

Yes, wifi to ethernet helps if you have a bad router. Im using a wired connection. But agree to you.

depends if your routing is even bad at the first place

e.g you get 80 ping to california when you are in california to a certain server, and you get less ping to servers even farther away

True, but let's take my example, i live in another continent :P and i want to play in another continent because players of my continent aint that good.

That's my case. And that is why I think VPNs can come in handy,

I get 15ms -30ms if i play local ( i mean within my country ) and gets 60 ms if i play within continent ( that is Asia )

won't help

That's bad :(

actually guys, i did give it a try, and made a small video,

I would like you guys to check it out too.
