First off my gear is 498 ilvl and I have around 18.77% Haste, so not too bad. Ive gone to sites like Mr. Robot to sim my gear and it still tells me that Haste gems are the way to go over Strength gems for 2H Frost. If this is true though then how come a lot of BIS DK's in top guilds are using Strength gems over Haste gems? I even punched a couple of them into Mr. Robot and it said that they need to switch to Haste gems. So should I switch back to Strength gems? Which is better?
