Sorry this is taking me so long. Been getting more work IRL and RL comes first. I looked through alot of gear to see how sets would match up, and from the way it looks atm SE has 2- or 3-piece sets max atm, with hands and feet not matched up atall with Head, Body, and Hands. This won't stop me from doing what I'm doing, just going to make more work for me.
But, as a heads up and suggestion from other players looking into this, how about 4 level 1 sets, one for each Discipline (War, Magic, Hands, Land), then a set per level starting at 5? The way things are looking I may make up completely new pieces for the full sets, but I myself would rather see alot of currently-released armor be added to to make sets.
Also, R01-R10, set bonuses would be extremely small to keep balance, maybe +1 to 3 different attributes or +2 to one, then increase by 1 every 10 ranks (+2 to 3 different attributes or +4 to one R11-20/ +3 to 3, or +4 to 2, or +6 to 1 at R21-30/etc.)
