Okay, fine. Here's some criticism!
First of all, this game is based on stun. It is literally the kind of combat this game uses.
Also, there is a block and pb for a reason. You can avoid being stunned by blocking.
In regard to Flame R:
Notice how flame R has really short range? Stay out of it's range and you are fine.
Perfect Block any attempted m1s to avoid getting trapped in an inf.
In regard to Love M1:
Love users have long range, but that doesn't mean their stun is unfair.
While they can go around blocks, they are STILL blockable.
Thus, block. Serpent's stun is really close ranged, so just pb any m1 attempts or stay farther away.
In regard to Serpent T:
Just like flame, this move is really close ranged, and it has charge up if I remember.
The long stun is pretty much punishment for not dodging while you could.
In regard to Nichirin M1s:
Nichirin m1s are fine. It is balanced simply because they are easy to pb.
If you cant pb m1s then it's not the game that needs work. It's you.
