I used to be able to start a server that only allowed players below a certain tier.

Is this no longer possible? Will it be added in the future?

It's more enjoyable for me to play with players of the same skill level.

Also - I prefer ffa with loadouts and I understand the only way I can start a ffa server with loadouts is to run a dedicated linux server(which I do not have). Is this correct or is there a way to do it on windows?

a side note - I've played a few ffa games and they turned in to a bunch of mg fights due to a dearth of weapons in the map. I didn't like it much.
