I don't have that problem, but then again, my gear is that of a casual gamer, meaning pug25's, ulduar10 and whatever else I can buy for emblems. I have 26 expertise with SoV and I'm hit capped with Edge of Ruin as my weapon.
The thing is, the further you get in raids, the more you get ArP and haste on your items instead of 'traditional' bonuses like crit, hit or expertise.
How I see it is like this: You have to ask yourself how to gem. Yes, every ret pala who reads game forums will say you should gem strength and nothing else, but you already have LOADS of strength on items and you have a ton of sockets. Switch around in your items, see how you can get to 26 expertise (with or without glyph) and then just gem accordingly.
If you ask me, gemming purely strength is for players who don't have gear for anything else. You have the gear to experiment - break the system, find your own way
