We all knew Legacy was going to be terminated eventually. It's only a matter of time before those servers cease to exist. I give it another 6 to 12 months before it happens.
Even without the server maintenance, it was never a guaranteed thing. They already said they would have one on the 20th for us, one weekend of not having one isn't going to kill anyone.
Evo Events never have been a guaranteed thing. They put them on 95% of the time over the weekends so missing one weekend every now and then isn't hurting anyone.
