Inc nades should have animation just as long as molotovs.
There isn't a single balance reason why inc nade should be better then molo in this regard.
30 muni + 80% muni income for all thrown inc nades, vs single time upgrade and 15muni molotov. I'm ok with animation time, i'm not okay with price.
Also R.I.P. British emplacement, bofor damage nerf was needed but brace nerf is just overkill, people learned to counter it...
