Reaper Best-in-Slot
2.5 GCD BiS
2.49 BiS
2.48 BiS
If you are looking to optimize around a different GCD tier due to either fight specific optimization or personal comfort feel free to ask for set recommendations in the Balance Discord.
Pre-raid penta-melded set
Run with this set if you are looking to get into the raid tier with the best optimal gear. This is a 2.46 GCD set, so your Plentiful Harvest may clip on your opener if you aren’t doing the early Gluttony adjustment.
Replace pieces with BiS tome and raid gear as you get them.
Pre-raid Economy set
This is another pre-raid set with a significantly lower cost. It is about 4-5% damage behind the penta-melded set. This is a 2.5 GCD set so Arcane Circle will drift .5s every 2 minutes, replace a single determination meld with SKS if you want to play at 2.49.
Replace pieces with BiS tome and raid gear as you get them.
