This is my key configuration after the removal of decent skills. I would never put the decent skills together in one macro due to interferences from other classes in my party.
E = Combat Orders, power guard, and weapon booster. Why? I placed all three in one macro because their end time was nearly the same.
F = Holy Charge. Why? To see my message when using the skill.
B = Maple Warrior. Why? Same thing as above.
X = Power Stance, and iron body. Why? These two skills last for 300 seconds each. And even though I have 9999 defense, I use iron body for its animation.
When I had decent skills. I placed them all in separate keys except speed infusion. Decent SI went with my X macro.
The rest of the keys are useless to me as listed in the very bottom of my screen shot.
