Please stop posting EP weights to people asking questions like this.
EP weights assume you have FULL 25man optimal raid buffs for a rogue to do as much dps as possible (every class buff possible).
If you don't have the "perfect" setup that the EP weights REQUIRE, then they aren't a solid piece of information to follow.
Being lazy has nothing to do with geming ap/agi lol, this is flawed advice and apparently the lazy rogue that isn't researching is the one spitting out this information to you.
The difference between AGI and AP gems is typically less than 1dps, and sometimes only 1-2dps, usually it's fractions of a dps. Sure 12 of one gem might equal a total of 6-12DPS! but still, it's a dismal amount per. Grab vulajins spreadsheet from elitist jerks and put your gear into it, take all buffs off or put certain buffs that you typically run with, and play with how to gem. You might find that expertise, or a hit gem might be a higher dps increase for you.
If you are hit/expertise capped, then it doesn't matter too much which gem you go for (ap/agi) but spreadsheet will tell you whats best. Just be careful, each gear upgrade you get could change which gem is better for you at that time, and if you need to be perfect, then it will require a full regemming every time you get a piece of gear. Obviously there is no need to be perfect, it's mostly about preference. Some rogues like to see the big AP number.
Isn't funny that the rogue that makes the rogue spreadsheet is using full AP gems? Oh wow, even the rogue that created EP weights is using full AP gems..... Guess they are lazy and didn't do their research like you did Feyras...
