"You may use any class and any gear. You are not allowed to use mounts and pets that are either paid access or limited time event rewards."

I have seen some people using paid mounts or limited ones, are we allowed now to use them ? I don't know too much if they have the same speed as the free one.

Hitboxes are definitely an advantage. It would not be fair to allow paid mounts (some of which unobtainable too!)

I've noticed some mounts can jump higher than others (pegasus) or even float over some gaps (cloud) even if speed is no longer a differentiator. I think boarwolf + no pet would be a good "non-juiced" standard if the community wants to make one. The best zero armor and weapons are relatively easy to obtain or borrow from friends.
