I hope Tungar gets a rework. I have not found any combo use for his neutral attack, so it's up-attack all the time unless I want the down launcher (up also launches). Zebei's also kinda simple but at least his neutral attack is a good combo extender to lengthen the timing window on juggles (but his up attack does more damage and has more meter gain... I haven't calculated the action refill times, that's more difficult), his down attack sees use for AoE, and his fast action refill guarantees his part in combos.
