WvW solution: Kick out players
If they kicked everyone from a server that had a higher population to give it the same population of the lowest server of that match up then most people would complain. Why should higher population servers be punished for a match making issue? Its not that servers fault that they got matched up with a server with a lower population. And I can imagine what the lowest population server of that match up would do.. Have a small group of people (just enough people to take an undefended keep) and stay at that amount of people. Ask anyone to join to leave (Trash talk them if need be) so that the other 2 servers can only have that amount of people and they won’t be able to defend properly.
Also with servers that don’t have a NA prime time. Why should their players be punished? If a server had a Oceanic prime time while the other two servers had a NA prime time. The Oceanic prime time server will only be able to have a few people in it. When tons of people are wanting to play WvW, Only a few will be able to play it. Also, If a guild from the lowest population server logs out, 20 people get kicked from the other servers. It would cause so many issues so this would be a very bad idea to implement.
Some servers have different prime times than others.. No need to alienate and punish them for it.
That would make NSP win nearly every match we go against. We’re almost always Outnumbered yet we hold our own (and even win a lot).
