Do you guys think it's worth using the 4 piece? I was thinking about how I often use TFT and mostly it's for burst phases which occur every 1 min or so, thus the reduced CD in TFT doesn't really make a difference (in that regard). Surely it would be better to skip getting the mastery shoulders or helm and just go for another crit/haste item to improve the throughput of the 2 piece instead? I would definitely run 3 pieces: gloves, legs and chest but I think the haste shoulders (from Horridon) and the crit helm (from Megaera) would be more beneficial than the mastery shoulders/helm.
