Now that we are in the 4th version of FFXIV wouldn't it be fun to have some gear that have set bonuses? Set bonuses have been in FFXI and in FFXIV 1.0. Basically if you equip enough pieces of gear from the same set they give you an extra bonus.

Like for example if you have 2 pieces of raid gear you get a bonus, at 4 pieces you get another bonus. And the bonus doesn't have to be stats but like a special effect. For example maybe for a tank having 2 pieces of raid gear would give you 20% more chance to parry and getting 4 pieces would make it so you would counter auto attack when you parry.

Or how about weapons that have special traits or procs. Stuff like a sword that occasionally attacks twice, or weapons that have an HP drain proc.
