Blake's combat and reaction speed is higher than wind's even with the enhancement so I'm not sure how Enid would have an advantage there
While not outright teleportation, Blake does have got mobility options as well seeing as she is able to use her clones to launch herself several hundred feet as well as using her gun as a grappling hook and slingshotting herself with it (see the fight with the sea feilong for reference)
Gravity Resistance wouldnt really help here, blake doesnt use it to do anything gravity related, she just uses it to amp the power of her attacks.
Trying to restrain Blake wouldnt work, she can just escape with her semblance as she has done several times in the show, and Enid trying to restrain her physically would just get Enid blown up and set on fire, electrocuted and paralyzed, encased in ice, or partially trapped in a stone statue which then explodes and stuns her.
The only solid advantage Enid has is the range with her fireballs, but at that distance coupled with Blake's higher speed and skill in dodging and sniping incoming attacks out of the air she shouldnt have much difficulty at all working around it and closing the gap while also returning fire with her own gun and blade beams.
