Horrible ping, is VPN allowed?

[wilaw1115]

I play from overseas and am getting 250-300 ping with lag spikes here and there. Normally this isn't an issue until I start kiting mobs. Long story short: plenty of deaths resulting from inconsistent ping. So here I am.

I'm sure VPN would improve my speed and decrease lag spikes... but given you're not allowed to 2 box here, chances are there might be people using same VPN as me and we might end up playing from same VPN IP address which would qualify us for a ban...

Is there no cure for my disease? Or is doctor VPN ok here?
