I too voiced my displeasure at the Overpower change because it was boring and unnecessary, but let's not act like it really matters. Old Overpower had some advantages, but so does new Overpower.

The real issues with WAR are DPS (along with PLD) and critical/direct hit rate raid buff anti-synergy. Nascent Glint not catching the WAR's 4th GCD is also poor design, but it's a minor issue.

I'm not one to care too much about job complexity or difficulty, but given that WAR's difficulty was eased even further in 6.1, it could probably stand to gain another ability/mechanic to juggle in the future.
