MNK gains tp pretty slow compared to two-handers actually. (MNK/WAR maximum time to 100% at capped haste: 23.8, WAR/SAM maximum time to 100% at capped haste: 9.6s)

But then, MNK focuses more on TP rounds or "white damage" rather than WS. (as in that's where most of MNK's damage comes from)

However Counter+Counterstance+AF2 feet is already 25~35% more counter rate than retaliation, making the white damage you actually gain from countering much more significant than what WAR gains from retaliation. Plus the fact that you don't take damage during a counter kind of solidifies the fact that counter is good as is. Counter keeps the job at a high survivability standpoint, where as WAR has next to NO survivability.

Tactical Counter as a JT in the future? Possibly. I don't think anyone would argue with 2~3 TP a counter.
