Guild Wars 2

So if there’s a tie at the end of the season do both servers get the first prize? Or are they going do points for against or another way to decide the winner?

They both will receive rewards for the the spot they placed. So if 2 servers get first place, they both get first place rewards.

They will either give both servers the reward or base the tie-breaker on something like server rating at the end or some other method.

The one this that is pretty sure is they will not extend the duration of the league to break a tie.
