I hope in 4.0 we can start to see set gear, for example with 2 pieces u get a + 15 Str bonus 3 pieces extra Vit , 4 pieces Your combo gets a extra 100 potency etc etc. Id also like to see the need for elemental resists. You could have a vendor set , a duty dungeon set , a raid set, and a Grand Company set ( similiar to what is in place for low content gear). Im a tank I like to crunch numbers and balance Mit vs dps this would add another layer of that for me. Plus we could have cool class specific bonuses like 5 pieces of the Whm set removes the mp cost of holy or 5 pieces of the PLD set adds 15 sec to Fight or flight. I think this would be fun and add more reason to raid and run dungeons for set pieces.
