I'm happy to see a little bit of interest in this LLD forum.
Very few people make MLD kickers, as they really aren't viable in either melee or vs. casters.
Vs. Melee - Although LLD kickers can hold their own against certain builds. In fact, they are the perfect counter to the otherwise king-of-melee Conc Barbs. However, with the introduction of Oath into MLD, their damage pales in comparison to all melee chars. With the introduction of Shaft and Gaze, their Fade no longer makes them the only character that can get DR.
Vs. Casters - Although LLD kickers (especially LLD Ghosts) can fair well against casters, the level cap doesn't increase any of their abilities to compete with casters. While casters get 30 Life Skillers to increase their damage drastically (not to mention the fact that extra levels increase damage much more than pumping DTalon), a kicker doesn't gain much. 24 frame DFlight just can't compete against casters teleporting at 7-8 frame with this higher damage.
Back in the day before people were as strict about level caps, a lot of people would make level 57 sins so that Chaos could be used. However, if you made one of those nowdays, everyone would call you BM. I really can't think of a build that could compete with quality melee or casters.
