Yeah they do look alike a lot. What I did (PS4 player) was I developed a hotbar for what I thought would be comfortable for me once I got to level 50 and started building based on the final product from the beginning. So while I was leveling Rogue, I only used the cross class skills that would be available to me once I hit NIN (Protect being the one exception), and I left slot open for skills that I hadn't acquired yet. So by the time I get everything unlocked, I'll already be comfortable with where all the skills are placed, and won't have to look at them as much to figure out what's on cooldown.
