(Gamebreaking) Glitch Into Forbidden Areas Using Engineering Item (Patreon)

The great Lord Slaain alerted me to this exploit:

This item can access forbidden areas. Unlike most similar items and abilities it has no vertical constraints and can bypass invisible walls. I was able to glitch into multiple areas I have not had access to for years (or at least without using exploration techniques which require a lot of impractical set-up). 

The item is "Sticky Warp Grenade" https://www.wowhead.com/item=198281/sticky-warp-grenade. This is a simple explosive you can throw into a target reticle-the twist being that it transports you to thrown location after 3 seconds.

This item is unusually powerful. I was able to use it first time to do the following (these are just examples) in battlegrounds:

1. Escape the boundaries of Arathi Basin and Deepwind Gorge..

2. Access the Mage Tower in Eye Of The Storm.

3. Break through an invisible wall in the village below Stormshield. 

4. Get an early start in Warsong Gulch by throwing the grenade into the second story of the alliance starting area. I could also escape the barrens behind the Horde base.

There are many more examples. This cab be used for game advantages eg:

1. Hiding the flag in capture-the-flag battlegrounds.*

2. Accessing inaccessible terrain around flags in resource battlegrounds. 

3. Skipping trash/bosses in pve content.

It can also be used for very easy and accessible exploration into dungeons and raids - there are other methods that can be used for this but they are generally much harder to execute and set-up.
