Since pretty much every competitive arena player was a Jewelcrafter, patch 3.2 impacted almost everyone reading this significantly due to the changes in Jewelcrafting and how the Dragons Eyes are not prismatic anymore about wow gold. I know it is taken me personally hours and thousands of gold to fix all of my gear outfits (PvE tanking, PvE DPS, PvP). The hard part was not really buying the gems (although I spent probably around 3k gold doing this) but rather figuring out how to min/max my socket bonuses and meet my meta pre-reqs without the luxury of 3 free prismatic gems about wow gold.

It is far different for every class, but for I will make some recommendations for Death Knights: Only go for strength socket bonuses if you want to max your damage output. Skip everything else like crit, resilience, etc. Use 4 new epic spell penetration gems. DK PvP gear has a lot of blue sockets with str socket bonuses and 4 of the new gems will put you at 135 spell pen about wow gold (35 on cloak, four +25 gems). This overcomes auras and shadow protection without sacrificing much.

Pretty much every DK goes with the 3% crit meta, which is obviously best for frost (since it relies on crits) but for Unholy I prefer the AP/Run speed meta. This is because the amount of things that can crit for an unholy DK (basically strikes and white swings only) is very few and even a top end scourge strike crit will gain very little from this meta (7k ss + 200ish bonus from meta). Whereas having the AP/run speed meta can not only free up 2 talent points but also benefit ALL of your damage both crits and non-crits, as well as helps your ghoul and gargoyle scaling.

Finally, as general advice, if you are not the richest person out there, do not go lunging for new epic gems just yet about wow gold. Give it a few days or even a week and you will notice a tremendous price drop in them as more people get the designs and as all the casuals run their beloved heroics and fill the market with more gems via emblems.
