There's no Patch 5.3 thread for this yet that I saw so I figured I may as well preempt others asking the question.
What's the new threshold for dropping 4-set T14?
In my case, I have a pair of extremely minor upgrades but also have an LFR ToT helmet that I could use the metagem in (this will cause me to break 4-piece because I never got the pants). Is it worth dropping 4-set for the helmet?
