Since you seem to be quoting me, I'm going to assume you are addressing me...
Who said anything about being confused or angered by two rows of skills?! Maybe if you read the whole train of conversation instead of making assumptions out of context, we'd have a discussion.
You want to use 30 -40 skills per combat.... I average 2 skills per turn per character. Assuming you can never repeat skills, that's 20 skills in 10 turns. I've never had fights lasting longer 10 turns... Tell me again about the efficient use of screen estate, devoting it to skills that never get triggered in combat
Fellgnome is advocating for customizable macros. If you can't remember what skills you have, heaven help you because good luck remembering if 1221 is summon spider or if you set that to 1222.
