I am very sadface. :C
If you depend on rotation, then thief is not for you.
you need to use your skills to counter your opponent. combat doesn’t end after you do a rotation. it ends when either your opponent is dead or you are. a rotation will not accomplish the former. only skill (knowing what abilities to use and when).
If you have the trait that gives 3 extra initiative, then you also have the trait that gives you initiative on steal (I believe). So with that rotation, you are wasting good ini. Oh and thieves really do need to adapt, so preset rotations aren’t all that great for them.
