Im a daring type and i wonder if its ideal to put stats in both dex and power. Is this a wrong thing im doing and if i am, do i do a pure power or pure dexterity?

Hmm you will have a secondary stat anyway but you should really put your priority on your main kind of weapon if you use bow/twin swords use dextery, if you use sword/axe/oodachi use power

Focus one early.

Branch into another when you have like 90 of your main stat and affinity titles.

When I started, I thought I should increase dex and power, since the base Daring build included them both as the high stats.
I even dropped a point or two into other things, for SP, in my first few levels, thinking I should increase it.
Weeks later, I learned that I should focus just on dex (twin swords, occasional bow), and have put all points into that ever since then.
