I entered PvP with my level 25 alt. I thought it was the cap but I saw a level 30 and a level 23 mage. Isn't that a bit overkill? I mean a level 25 can host and a level 30 can join the other team.

This got me curious what is the level cap inside the arenas. If the host is level 25, a level 30 can join and not a level 31?

Thanks in advance.
