Thoughts on them adding a Fortification system like whats in Dota?

Simple discussion based around a Fortification mechanic such as what Dota 2 has.

If anyone is unfamiliar, there is team based active in Dota 2 where anyone on your team can activate it to make all of your teams buildings indestructible for 7 seconds against heroes then 4 seconds against neutrals. Really helps when a teammate gets caught out and the opposing team looks to turn that quickly into an objective before a response can happen.

Ive noticed many occasions where this would be super viable in Deadlock and personally think this is a must add.
