Not necessarily on the 'everything', because of all the Machinist/Astrologian/Dark Knight levelling. It really depends on how many of the first are being levelled. If anything, it might be like the weird Syrcus queues I was having last night where NO DPS WERE QUEUEING.Yeah it's max level, and it's a LOT of quests after that. You're probably not gonna make it I'd say unless you play an insane amount. Plus side is you'll get xp past 50 once the expansion hit. Downside is you're gonna have to do 50 trials and shit while most people will be doing other shit, which is going to make the queues even shittier, and you're a DPS so you're probably going to have like 40mins queues for everything.
How is it poor design, expecting you to finish the story so that the reason you're even going to Ishgard is valid, rather than handwave and POOF, a magicalcontinenthub appears!
