Exactly as Soraweczka said: I see scorched feet as a benefit, tbh...allows you to get out trouble fast and or just move around quicker in general. You know exactly when it triggers so you can just aim it as you blast through the zone.
I saw a video where you can actually run around all of that, but it's through the out of bounds area and is very risky however it saves a crap ton of time. With split and haunting its way more risky soon as I kill Misha and the adds afterward, I wait for the next split and haunting and run on the rocks and up over the water fall and up it places you right outside Rexxars' pen to the left.You'll still need to kill a knockback bug however after killing Rex it's easier.I've used it a couple times, but as I said its quite risky. I've done both 5 masks as a lock so it helps a lot.
