Randomised stats is dumb because it won't really be randomised. You will just produce enough so you get the good ***. All your doing is filling a hanger with crap when you could do the same thing by making the cost more expensive.
Do you really think to fit a mesmer you would make six and then go 'oh well, three suck'. Of course not. You just make enough so that they are all good.
On top of that you really don't want to be adding something incrementally better. T5 should be about trade off bonus. One aspect of a weapon is better with a contra aspect worse. Think double the alpha, half the cycle time for instance.
Proverbs 23:20-21 warns us, “Do not join those who drink too much wine or gorge themselves on meat, for drunkards and gluttons become poor, and drowsiness clothes them in rags."
