It's currently possible to kick somebody as a feral druid with your "Skull Bash" when you are on the 1st floor of the arena and your target is on the 2nd floor of the arena. The only thing you have to keep in mind is that you need to be in range to charge. So make sure you're close enough. It's not working as intented because this is not the feral charge (the leap one) it's the direct charge (kick replacement for druids) and definitely gamebreaking espacially in 3v3 as a school lockout will do much.
You can also use it to save your ass when you're getting nuked, so you can escape on the top floor.

Tip: When you're playing with a priest tell your priest what you are going to do and let him instantly grab you back to him, so you won't lose time while traveling up.
