I'll have to get home and mess with it, but they are saying you can just duckblock kitana rushdown? I am pretty sure she does have an overhead? The top player in our MN tournaments is kitana and I am pretty sure just ducking and blocking gets me blown up. I am trying to find the correct gaps in the rushdown to tele out with raiden lately.
She has two overheads. The second hit of f+4,1 and the second hit of b+1,2.
If you crouch block f+4 it usually whiffs and you can interrupt her. Only on large characters at point blank range will it not whiff, so worst case scenario you have to stand up and block the overhead. The low option is just a sweep you can roll away after. That's why it's only done off a JIP.
If you crouch block b+1 you can easily stand up in time for 2.
When you crouch block you can blow up all the cutter setups. 2,1~cutter, b+3,3~cutter, 1,1,2~cutter ect can be ducked and full combo punished if you are crouch blocking. On small characters many will whiff without even having to let go of block. Cutter is also not neutral on block if it's crouch blocked.
