none of these changes will effect BA at the highest level imo, now only the scrubs will have a hard time using him as there 13th character behind their 12th...superman. lets look at the changes,
divekick more unsafe, but like seriously what BA uses regular divekick anymore?
MB lightning still is a good meaty on their wake up, and its safe not +8 but that never mattered. his regular lightning now has a decreased hit box, and now it gives BA no real reason to use it since it won't catch anyone jumping last minute but atleast its still relatively safe on block at a distance.
his back dash recovery is a few frames slower now, and the range of it is reduced, this is by far the biggest nerf imo, now he can't run away as well and BA players have to play smarter.
his orbs have more cooldown and have less active time. so now its normalized, before it came up like every 5 seconds to add un blockable damage when you are on defense and added damage to hit combos sort of like other traits. now at the end of the game he can't just automatically win now, we have a chance to make it run out and then approach him.
damage scaling is whatever, if superman and flash gets damage nerf i don't wanna hear BA players cry about this.
now he got 2 buffs in this patch, more hit advatage on one of his combo enders and the MB Black magic you can probably now do a b3 and it will bounce them off the wall when before you couldn't so more damage on his BnB's???
any BA players stop crying, he will still be top 5 or two 3 trust me.
