this is so not true lol, first off there is multiple situations where only a dodge will save your life, going from a death to a survived hit, 4p is literally a free 12% dodge every 60 second, a gcd which i will gladly take considering using 1 gcd for a defensive is perfectly fine as a paladin tank,
2nd- you lose barely any armor for the tradeoff, if you simmed or used both builds you know what im talking about, the difference is barely 650-700 armor and a small to un-noticeable defensive stats, i will gladly trade 700 armor for 12% dodge every 60 second, there is literally no point why you wouldnt want to use 4p.
if you go and say yeah but hit will be a problem on 4p, no it wont, you use lady helm bringing you to 7% hit + 1% draenei, u can bind bvb to your taunt if youre horde, or hit food.
