How do newer players build their skills if any content before hw is considered Old

[kuma_aus]

Just because it's old content doesn't mean that people won't help you clear it like normal. Remember that the Duty Finder matches you with randoms. Some people you match up with really just want the clear and don't care about helping. Some don't mind helping. The best thing you can do is use Party Finder and get friends and your Free Company to come help you clear. With Party Finder you can clearly state your goals so people who join know exactly what they are joining for.

The current tiers of content:

Alexander (The Creator) normal is more than enough to cut your teeth on and learn the bare basics of your class and how the skills work. Even if you're totally lost the content isn't hard enough the group will fail if you're fumbling around and getting your bearings.

From there you can step up to Sophia (Extreme) which is a relatively forgiving fight, which will get you past the basics on movement, reading boss tells, and coordinating with other players.

From the first parts of Alexander(The Creator) savage pick up about where Sophia leaves off.

Honestly the current crop of content has a very good learning curve for a freshly-60 player.

If anything the older 50 content isn't going to be great for learning basically it'll be either sync'd and locking you into a pared-down move set that isn't super relevant anymore or it'll be sync'd and be so easy that the mechanics aren't particularly meaningful. This is already true of fights like Ravana Extreme even at 60, damage is so high he just dies before he does any of his interesting mechanics.
