Hi! I have been checking this thread time to time. After reading some of the recent posts about Makoto's 1.1 damage, I decided to create an account and share what I've found.
Meterless 4441 dmg - 6C starter
6C > 214AC > 236D > 2C > 2D > j.B~D > dash 6A~6B~C > 5D > dash 5CC > j.B > j.B > Corona Upper 5178 dmg if you cancel 5CC into Particle Flare 4292 dmg - 5B starter (Note: 6A~6B chain doesn't work with 5B starter)
5B~6C > 214AC > 236D > 2C > 2D > j.B~D > dash 6B~C > 5D > dash 5CC > j.B > j.B > Corona Upper
Tips:
As many of us already know, 6A and 5CC pick-up doesn't work on sliding Jin/Valkenhayn.
Instead: 4299 dmg - 6C starter
6C > 214AC > 236D > 2C* > 2D > j.B~D > dash 6B~C > 5D > dash 6C > Corona Upper * Note: after 236D, picking up Valkenhayn with 2C is very risky (Makotos 2C often crosses under Valk while he falls, thus dropping the combo). I wouldn't risk it, just go with 6A instead (or try the combo below).
I haven't tried these on the entire cast, but I can imagine dash 5CC being more difficult on smaller characters like Carl.
Sadly, 2C totally whiffs after 236D on Tager. But my old BnB variation works and deals more damage than just replacing the 2C in the previous combos with 6A (read below).
Reliable combos on Valkenhayn and Tager
(This variation doesn't work near the wall on Jin - 236D > j.B whiffs above him. His hurtbox lacks height for some reason.)
Valkenhayn - 4205 dmg (about 100 more damage than doing the previous combo with 6A instead of 2C)
6C > 214AC > 236D > j.BD* > dash 2C > 2D > 6B~C > 5D > dash 6C > Corona Upper
Tager - 4304 dmg
6C > 214AC > 236D > j.BD* > dash 2C > 2D > 6B~C > 5D > dash 5CC > j.B > j.B > Corona Upper
* You can run from a corner carry splat and hit j.BD in time, except not on really low wallsplats from max-range.
I hope these combos comes to use, or at least gave you ideas. I think these are near optimal combos. Please tell me if you find better ones.
