They don't deserve to host because A) their router doesn't support port forwarding (there are some that don't) or B) their parents refuse to let them do it or C) it's too complicated?
Hamachi may be a nuisance but it's not that big of a deal. The people that use Hamachi aren't at fault, they are just trying a last attempt to enjoy a computer game online. Grow the forget up and ignore the posts they make about it.
what i mean by that was:
If you don't know how to port forward, you don't deserve to host.
if your ISP, in visage's case, literally DOES NOT allow you to port forward thats different
but hamachi is annoying as forget, i have to use it to play my friend's garry's mod server and it annoys the piss out of me.
