Theres not enough macro space to play Ninja.

[Adamantium]

Initial FireIII coming out of UI was 0 mp due to firestarter, you now have enough mp for TII at the end rather than TI. Happens almost 30% of the time if you are under 251 PIE.

You're right. I was just thinking in more general terms. Having a 30% chance to have enough MP for T2 at the end of your Fire phase doesn't make up for how clunky a macro makes skill usage feel, in my opinion, especially with how small a DPS increase it is to use T2 over T1.
