So where is the complaint? Mind sending a link to the thread? Because right now it sounds like a loud minority.
Gee, maybe we should actually look at why people don't like playing healer? An idea: Try hitting your 1 Button 14 times every 30s and see how you feel about it. Yoshida says it would be good, but it's understandable why they are averse to changing jobs because you're essentially having to relearn the fight on that job. It's no different when you swap from Tank to DPS to Healer - they're all different roles and take time to learn the fight timings for - however, they time gate Savage and Tomestone gear because guess what? It retains their base in a patch for subscriptions. Gotta pay the bills somehow as a company, and also have a good budget for the next expac. If you could farm out all your gear in a week, Savage Raiders would be gone rather quickly.
No, no, and NO. The reason why is if we turn the clock back to Stormblood Launch, we have Tanks that were using Strength accessories to keep aggro, because all other accessories in Stormblood were inferior due to not having Strength included on the gear. We don't need this kind of crap again where substats actually matter since Vitality/Job Main Stat are hard locked into gear. Like, imagine a WAR taking Melee Accs into a fight...
Not sure how you increase versatility without investment into a job. You can gear it all you want, but if player skill is the issue(which is a good handful of people in Savage atm) then it means that you need to learn your job more and practice rotations. Learn how to plan out your fight and add muscle memory. In regards to Rinascita Gear, the prices have gone down since Raid Season is pretty much gone due to the fact that we've been at this for a while now. We're going towards the lull in content. Also, 610 is acceptable as long as you know how to do your job and perform well. Gearing only matters when you aren't geared for the fight's iLv req.
Yeah, that precedent is essentially when XIV is gearing up for a new expansion coming out. We aren't gonna hear about it until Fan Fest next year. Also, this 'pressure' you imply here isn't true - there is absolutely no pressure whatsoever. Grind Tomes Weekly, work towards BiS, heck if you know how to craft go ahead and craft your Rinascita for the 610. The reason people decide on i612-i615 is because they have higher expectations and want an easy fight, when in reality you can complete the fight in i610 gear if you do your job well and follow mechanics. That simple.
