The armor penetration in the upcoming Patch 3.3.2 is of wide concern by WoW players. Ghostcrawler has posted an early notice to players who plan on investing in armor penetration gems in a recent forum post. Armor penetration (ArP) is being nerfed, you'd better rethink your raid or WoW gold farming strategies.
Since Cataclysm has announced, everyone knows that armor penetration will be completely removed from the game, as it has been deemed confusing in regards to its use. It will be gone along with many other stats when the future expansion, but this preemptive change is a bit of a surprise.
Ghostcrawler said that the developer team noticed AP classes like Hunters stacking the stat too heavily, via gems and other means. "The nerf to armor pen in 3.2.2 is intentional," he wrote. "Compared to the recent buff where we increased the value of armor rating to 125%, this nerf would take it back down to 110%. While we are still evaluating the effects of this change in the 3.2.2 build, we did want to let you know of the possibility in case you were about to spend a lot on armor pen gems."
Armor penetration is being nerfed down to make it less viable as a single stat boost for those who actually understand it. However, gear Gemming won't change at all for most ARP stacking classes. They will still gem to the soft /hard cap then gem STR again or AGI again. Only this change does is nerf classes that use it dps. For the most part, this only affects raiders who use the stat to increase their DPS a little more easily than with regular stats. In arena play and whatnot, the odds are that the stat is going to have minimal effect other than to keep some players alive a little longer in the game than others-i.e. clothies.
Anyway, things will be completely different when Cataclysm releases next year. We will keep an eye on the WoW patch news as well as the new expansion updates. If you need cheap WoW gold to support your game, we are your best choice.
