no, its better going attack, then strength, then defence because you will level up an individual skill in 1/3 of the time it takes to level it up the other way. Basically, heres how it would go
-----A---S--D
with controlled, it would be
------------ASD
The skill that you level first would help level the other two. not by much, but by something, and if you do 10 levels instead, it can be noticed.
