As a collie main, Why did Devs nerfed flask instead of buffing ignifist?

Ok, so as the title states, why did devs not just buff Ignifist to auto-equip and increase the chance of hitting instead of nerfing the flask to the ground? I know the flask needs some nerfing like decreasing the range a bit but not this much in my opinion ʅʕ•ᴥ•ʔʃ
