As a lightning main, my attacks do multiple hits sometimes. Not that it matters. I think the damage gets evenly distributed or something? I've seen single hits do just as much if not sometimes more damage than a 3 hit combo. This also could have something to do with the *ion stat as well though.

While it does sound like I misunderstood you, you either misunderstood me or are just plain wrong on this one. I thought you were talking about single attack combo triggers. And in a single attack, if you do manage to do a multiple hit the damage does get distributed across the hits in some way. I've seen ninetails get hit for on a single hit basic attack for about 10-15K from main. If he procs the multiple hit combo on a single basic attack, that number tends to drop to as low as 4k. But because it can be as much as 3 or 4ish strikes in a single basic attack, it multiplies back up to around the original value.

That all being said, I mistook your usage of the term hit combo anyway which Daiske managed to cover.

I'd also argue that a lot of 10 hit combos on tails are pretty over rated anyway. I use Sasuke for the barrier in ninteails, but his ten hit combo when it does proc hits for maybe 3k. Sasuke can basic attack for over over 10k. These numbers change with power level, but it still gives a relative disparity between the damage gap. So it's pretty eh.
