FFXIV end game gearing is pretty relaxed compared to WoW's.
Essentially during an expansion launch or during a new tier update it basically goes;
Expert roulette/tome farm for the early tier gear pieces
EX Trials for accessories/weapon
Savage to upgrade to your cap while mixing the tome gear upgrades for BiS.
There's also crafting if you're a omni crafter or stupid rich and can get the pentamelded crafted gear with 5 materia slots or whatever it is. Those are really good entry gear.
The savage raids are more difficult than the extreme fights. Find yourself a static group, don't pug that stuff. It takes time to practice and learn the fights, but you'll get it if you give it the time to learn.
