Don't keep your range with tall people, that's what they want, they have more range than you. (by the way, i am tall so i have a tad bit of experience). Get in close, inside there reach and use short range attacks, most tall people get stacked by that, they're usually not used to having a little short person standing in their face(or chest) and trying to wail the hell out of them.
