Gibraltar's ult doesn't damage allies

Friendly Fire doesn't deal damage (You can kill yoursellf tho.), but the debuffs apply nevertheless. So you still want to avoid a friendly Bang Ulti.

agreed , that heavy bombardment is useless , its good , if you knocked down 1 enemy and then you use it on him because his team gonna revive him . that way its very effective . 

IF they make the area of bombardment  is same as BANGALORE, then it would be great. 

otherwise its useless.
