I used to be really into WoW's PvP during MoP. Loved during RBGs and 3v3 arenas. Racked up a lot of vicious mounts and a few titles.

In FFXIV, I quite like doing my daily Frontline. I especially love the Coerthas and Naadam maps. Don't really like the Cartenneau and La Noscea maps. Also kinda disappointed that there isn't really a competitive Frontline scene. It's not like WoW where you can see your rankings, or earn really fancy gear. That's what the Feast is for, but... nobody does the Feast. From what I've heard it's just win trading at preset times. So you can't really hardcore do PvP in FFXIV like you can in WoW.
