Completely new and learning

[SoulEchelon]

First off, welcome to FFXIV! <3

Before you start getting into dungeons, I highly, HIGHLY suggest you do Hall of the Novice.

It starts at level 15, and shows you the basics of your current role: Tank, DPS, or Healer. You'll be rewarded with some good gear that should get you to about level 20-25 and an exp boost ring that lasts until level 30.
You can find Hall of the Novice npcs at all the main city Adventure Guilds (The places where you start your first quests in the game. Usually situated at the inn or tavern in these cities). Its headquarters is just outside the first dungeon in the game. a big green symbol with a golden budding plant will be hovering over the head of the npc in question.

There are also things called Guildhests. https://finalfantasy.fandom.com/wiki/Guildhest

These are basically really really tiny dungeons with certain goals in mind. The first few are "Kill all the things and don't die", and you'll be paired with other people. I highly suggest doing the first few before you dive into the first dungeon so you can get a handle of aggroing enemies and keeping them all in check. That said, don't be disheartened if you see your dpses (or sometimes even healers) running off on their own. They're new to the game and will eventually have to learn the hard way to stay with their tank.

When you do finally get to the first dungeon, make sure to tell your team that you're new. The way FFXIV keeps older dungeon content alive is by giving higher level players the incentive to do them by way of the Roulette system (which you'll learn about later). Some times these higher levels forget that lower level players are still a thing. And don't expect higher level players to carry you either damage output-wise, as everyone's gear and abilities are nerfed down to the level of the dungeon/instance in question.

Other than all that, practice! With Paladin, don't hesitate to use your Flash ability whenever needed. Keep it in your ability rotation. Make sure you're attacking the enemy your team is attacking, and then add a Flash once in awhile to make sure all enemies nearby are focused on you, because eventually your Healer will aggro the other enemies you're not attacking due to their healing.

Not much else to say I don't think. Do your best, and above all - have fun. That's what it's all about.
