Meterbuild nerf barely affects him because he still has decent enough stagger pressure to build meter with, blocking mine still builds him good meter, and he doesn't need meter in the same utility as someone like deadshot. Despite meterbuild nerf, he can play exactly the same as before unlike Deadshot.
Lunge nerf is a slap on the wrist. MB lunge (the only Lunge you should ever be using) is still safe so have fun. If you are using regular lunge, you deserve to be punished.
Batman and Deadshot nerfs completely changed their gameplay which is why they moved down the tier list. Hood's nerfs however, changed absolutely nothing about how he plays. You could literally go in and play him without knowing there was a patch and not notice much of a difference. And since previous patch Hood was Top 5 and he essentially stayed the same as previous patch, he is still top 5.
