I would love to see it back for a few game modes to be honest :p
And for those saying 1.9 pvp is more balanced for the lesser skilled players to have a chance, it really isn't. If anything if you aren't as good at it you have even less of a chance of beating someone if they are at least decent. The most they will get is a panicky spam click hit.
At least in 1.8 the spam click hit would actually do some kind of damage. Just saying...
Also Cubecraft wasnt really made famous for its 1.9 game modes, it's was already well known before :p it was hitting double the amount of players before it updated to 1.9 ( 30,000 and growing ) while it was a 1.8 server.
It's only known now for being 1.9.
