Hard to say without an armory link. What do you mean by "hit issues"? Are you missing taunts? Is your threat low?
In general, I wouldn't worry about hit unless you are repeatedly missing necessary taunts. Then you can either glyph Dark Command or switch a piece of gear out. If you look at the armory pages of many MTs, you'll see their hit in the 120-180 range which is fine.
Also remember that if you're dual-wield Frost, you actually need less hit because of Nerves of Cold Steel.
