I started playing when 5.3 came out, but I know that DPS used to have more utility. BRD for example had a healer LB3, casters could replenish someone else's MP with Manashift and so on. I guess they got rid of most of utility skills because of balancing issues.

It's not just a DPS only problem, either. Scholar and AST used to have more utility skills too, like AoE Esuna and Silence and Haste for SCH and all the different card buffs for Astrologian.
