Some later endgame content (raiding and stuff) will do this but XIV is designed to be a much more casual themepark style MMO and so its never going to be up to the difficulty of XI.

Leveling to 50 is especially intended to be easy. Titan at 34 is the first time you'll see multiple mechanics start entering fights, and then Garuda at Level 43 is the culmination of that prior to hitting level 50.
