Some classes are unfair.
Like the slime THERE IS NO WAY TO WIN WITH JUST FISTS
And the giant can spawn kill.
Ghasts get stuck in the small portal and all the sever host says
"Use the big portal" Its such an easy thing to fix.
And the Normal classes can't FLY
Slime has 160 health.
Giant can be attacked very easily and classes spawn in different places. All you have to do is jump around, it will be hard to hit you.
Use the big portal.
Can humans fly in Minecraft? I don't think so.
