I see your point that the character selection was purely about appearances. Hopefully they add the concept of requirements or synergy to the skills. Having Strength or Intelligence requirements prevents a player from becoming too powerful in several fields. I remember Diablo II's Druid had a lot of skill synergy. There were several skills, that while having unique effects, they also improved other similar skills, particularly in summoning. This would encourage the player to stay focused on summoning though there was still a benefit intaking some weather magic skills.
