Caps and gems interaction:
1. You need to reach exp and spell hit caps first as they get the highest score of 3+ EP, third best usually comes below 2.2 EP.
2. It is easy to reach those caps. If you go all out for those 2 stats with pre-raid gear (input 3.4 in lootrank) you will reach 450 hit 213 exp from gear alone. It is relatively easy to reach those caps using pre-raid gear with exp and hit being valued as much as best dps stat that sim suggests after exp and hit caps reached. However this require using all exp and hit gems, hit or exp consumables on top of that and few non-optimal enchants.
3. While your gems are split between exp, hit and dps stat – those stats are equal in EP value. You may think that you can decrease exp&hit value after caps are reached but doing so immediately requires you to replace all of your gems with dps stat wich in turn requires you to raise exp&hit value in order to reach caps again.
4. With current high-end WotLK itemization you won’t be able to reach caps from stats on optimal gear only with EP value less than the top dps stat. The better gear you get the more spread stats become and more sockets appear. Best dps 10-men gear with hit & exp EPs of 2 comes with 260 hit and 180 exp, the rest to be covered by gems (7 slots + 1 from BS for that purpose).
Conclussion – do not worry about caps too much when you start raiding. Run enhsim with caps reached. Find EP value for the best stat. Use same EP value for hit and exp. Get items based on those values. Use gems to adjust (at the very start of raiding BS with 2 additional sockets comes in handy). Use consumables (food first) if further necessary.
