These are valid points on paper but rarely a disadvantage in practice. When I alt-raid on WAR, compared to DRK, its a complete easy-mode snoozefest as far as stance dancing and the sheer number of buttons that need to be pushed.
The thing is, IB is so fucking worth the sacrifices you make for it. Its readily at your finger tips and stacking it with any *ONE* of WAR's other significant cooldowns (RI, ToB, Vengeance, hell even Foresight paired with a well timed Equilibrium) means you essentially have a huge tankbuster CD combo every 30-40s.
IB+RI - 30s - IB+ToB - 30s - IB+Ve - 30s - IB+RI - 30s - IB+whatever is left - 30s - IB+ToB - 30s - IB+RI - 30s - IB+Ve - 30s - etc. etc. ad nauseam. In between all of these they still have Zerk+Bloodbath, Conva, perhaps Foresight+Awareness, Second Wind, and every other Equilibrium, and extra IBs.
When people harp in-game on how well designed WAR is as opposed to using the term "overpowered" I instantly ask if they have every tank leveled and if they honestly don't feel like WAR is straight-up easy-mode on almost any fight in comparison. PLD is just a straight up struggle, and playing DRK correctly is like playing a DPS and a tank at the same time in terms of the number of fucking buttons you need to press ALLL the time. (Although in my opinion DRK feels the most -actually- balanced because I feel like it has the same degree of challenges balanced with power and advantages as most other non-tank jobs...) With WAR you have a cooldown for anything and everything and it just feels like minimal work needs to be done to survive. Even hopping into Deliverance while MTing for a triple cleave, you'll have RI and Vengeance up so even though you're out of Defiance you've got a 30% damage reduction going +100% parry rate, and these instances are planned around the pacing of the encounter so if a WAR is ever without one of those CDs for an upcoming tankbuster cause they were triple cleaving earlier, its the player and not the job.
It can do everything and it can do it so EASILY. I don't even play on my WAR that much, but whenever I do its like riding a bike it immediately comes back and its like "psh, i got this" whereas on DRK its like riding a bucking bronco (which is awesome in its own way) and PLD is just... annoying because the job is designed to play suboptimally because of enmity issues of all things.
