Demonic Gateway in Brawlers Guild [ Horde only]

So far I haven't been able to figure out how to use this and I know someone will bash it for not being a real exploit, but someone with more talent than me may be able to use it to their advantage.

A warlock gets on top of the large pillar in the Horde Brawlers Guild arena and summons a demonic gateway to any other spot on the ground. The near side of the gateway will spawn inside the pillar allowing anyone who takes the gateway to end up inside the pillar.

• Also works on piles of crates and anything else you can stand on in the area.
• Once inside, you can drop a demonic circle and move in and out freely.
• You can also rez another player using soulstone from inside and they will rez inside. 
• Being inside does not LoS you.
