MMORPGs, and then I mean creating a character that is of any help. I tend to follow guides to get a decent character, but have big troubles making up a build myself. I'm still proud of my Guild Wars warrior build though; that was almost entirely designed by me. The fact that in Guild Wars you can change your build in the blink of an eye, contrary to WoW where it costs you lots of money, stimulates creativity a lot.
Just for the heck of it, here's my Guild Wars Warrior/Monk build:
Lion's Comfort, Barbaric Slash, Gash, Dragon Slash, Enraging Charge, Whirlwind Attack, Radiation Field, Resurrect. Mix with 13 points in Swordsmanship and 16 in Strength, add a good sword and shield, and voilà! You got yourself an adrenaline-driven maniac who charges into every mob he sees and is the bane of any healer you might have in your team.
So yeah, another reason I'm not all that good at MMOs is because I tend to give the healers on my own team a hard time. The health bar is my biggest opponent, a boss I cannot defeat.
