There are a couple things to look for:
- What is the ILVL required to que LFD heroic dungeons?
- What is the ILVL required to que the LFR raid zones?
- What can you craft that has and ILVL equal to or greater than than one, or better yet both of those barriers to entry?
Second thing to look at is what is best in slot pre raid gear you can craft... if you can craft BiS gear that is also above the LFR minimum it is a big winner.
