Dream come true if so, but I'll main him regardless because that new jump attack is just so beastly.XD
I am thinking since he's basically been buffed to Chuck Norris and back, all with his attacks, attack speed, speed, air speed, grab, aerial grab, recovery, etc. He'll be a high to top tier.
Also, since his bombs blow up faster, Link's recovery has indeed been helped tenfold, and the bombs also have better spam-ability, meaning since they blow up so fast, you can simply throw one at your opponent, see it explode, pull out another, etc.
Link's experienced very, very, VERY minor nerfs. And one nerf in particular isn't even going to be in competitive play, and that's his Final Smash nerf. The bomb ''gravity nerf'', eh...that's not a nerf really, since I see no difference in throwing the bombs in this game compared to the others.
