4th job Single Target DPS

2.4*0.65 = 1.56
150% (TT) + 156% (crit) = 306%. It's an average, no chance of working.

I don't think thats correct because my non critical damages remain same. Only the critical dmg increased.

This is exactly why people always overestimate how much damage NLs do. They only look at crits. If Player A's max damage is 10k and Player B's max damage is 10k, but Player A doesn't crit, guess which one's going to do more damage (provided Player B doesn't have a 100% crit rate lol).

No i did 17k on 1 star and 11k on one star without se. Both were critical.
