Kotal is a character that tests his opponents reactions, predicting skills as well as how well you're used to punish the things he do.
A good piece of advice to anyone wanting to beat Kotal in neutral, head to training mode and tries to interrupt his advancing normals with your best normals..
2. explore all possible gaps on war god mixups and learn your best options for it, specially if you backdash it.
3.You can surely backdash his OH/Low mixup in wargod, it doesn't mean you should try to do it all the time, block punishing and armoring through the gaps can be a better choice in some stances. except of course if you're playing scorpion, you really have to backdash mostly everything.
I play Hat Trick and Ninjutsu Scorpion in this MU, Lao has a slower walkspeed, so either i stand my ground, or i jump backwards on correct distances when i predict a charge in, other than that, F2 is only -1 and helps Lao a lot to build up a counter or offense based on it.
With scorpion the neutral is much easier to control due the teleport-cancel and he actually has some good buttons to keep kotal in check with his offence in mostly any range.
