You're comparing 2 different games with 2 entirely different battle mechanics.
In FFXI, battle was more slow paced, we needed those abilities, not to mention a whole host of buffs and debuffs etc.
In 14 battle is more fast-paced, we aren't even subject to a lot of the same status effects etc, which makes a lot of those actions unnecessary.
The improvement here was simplifying and streamlining job abilities. If you want XI style battles, go play XI, it's really simple no?
Just because things worked in XI doesn't mean they will work here.
