There is a need for blitz grab hitbox to be smaller
Blitz grab is a fast projectile which launches with no warning whatsoever ( Unlike thresh hook ) and getting grabbed is EXTREMELY punishing with a chained rocket punch and ult.
The problem is, that side stepping the grab is almost impossible since its hitbox is too big. When u are at your turret, or at the enemy turret, both the times it is agitating to not be able to harass the enemy unless u have a long range poke since blitz will grab and chain you which will surely lead to a full blown trade, mostly ending in blitz favor due to his early pressure.
Making the grab dodgeable will be so much better decreasing its hitbox to match his small hand, because many times i have seen my ADC get grabbed by the sides of his hand. Or the projectile can be slowed down a little like thresh hook.
