Kung Fu master tank build?

[Sai Grey]

Should I follow the wind, fire or other? 

[Shuchin]

I recommend to customize your own build for tanking - actually to reskill dynamically for each and every opponent type you are facing.

That said, and not knowing the template builds by heart, I suspect you are fine with either as long as you play in a tanky style.

Staples for tanking:

Q/E all points
Counter stage 1 or 4-3
Tremor stage 3, tier 4
Fighting Spirit
points into 2RF
point into Guiding Fist if you have trouble keeping aggro

Once Searing Palm becomes available (lvl 45), there's many more things you might want to pick to optimize the pressure point aspect, but that's a bit complex.

Try to find the Freedom clan KFM guide on the net, it's pretty awesome. ^_^
