Hunter 2p makes not much sense. One spec cant use more focus because its burning slower away than refreshing. And warlock 2p and 4p is a slap in the face. 2p is only useable once in a fight mostly and not that strong as affli or destru. 4p is only usable 3 times by demo and destru if there are no adds to refresh shards. Some boss adds dont give shards by the way. As affli I can use soulburn seed to refresh but I waste 3rd soulburn which should give me the 4p "procc" only to use it 2 times more till I have to refresh.
