I wouldnt either unless a yellow socket is worth it for a good socket bonus, then its a toss up crit/dmg or haste/dmg, personally i would go haste/dmg in that case. Other than that i would ignore socket and go +dmg until enough is stacked. Thats why i capitalized only if you feel you NEED the socket bonus, as in the socket bonus will give hit or spell damage in about the same amount you lose on the split gem. Personally if you have to make a yellow and i should have said this before but dont know why i didnt think of it, put in hit/dmg (veiled gem) and change a hit gem elsewhere to full spell damage where you arent looking for socket bonus.
