So as the title suggests, I feel like there is still something that could be added to the game that would help fill in a gap that I've noticed. We have plenty of 5 piece, 2 piece and 1 piece (Mythics) sets, but I feel like also including gear that go up to 3 piece and 4 piece bonuses would really allow people to get creative with our builds.
There are passive bonuses for mixing and matching gearsets, but all of it feels pointless because those old sets are seriously outclassed by the newer sets, having more sets that encourage the diversity to wear a 3 piece and 4 piece set with a monster set, a mythic and maybe even pairing that with an arena weapon could lead to some really crazy and fun builds.
These are just my thoughts and opinion, but I see some potential for things to get better which is why I'm posting this. I would like to know what others think of this, so please share your thoughts.
