>>47761191brave bird only does ~13% more damage, and it's difficult to use properly with the game's aiming system. with how frail you are you can't really take advantage of the reset cooldown thing. and talonflame is supposed to be an initiator of sorts, so the stun from upgraded fly is very useful.
>you're just broadcasting to everyone on the enemy team that you're moving towards themby the time they see you coming it's generally too late to get away. like gardevoir in this webm.
>Brave Bird lets you engage from crazy far away with barely any time to reactyes but you're fully vulnerable and thus liable to just get hit by any stray moves or ults that are going around
>>47761195safer initiation, stuns when upgraded, nearly as strong, better for escaping
>>47761199so does flame charge
