There's a lot you can do to match the server and client. Hide as much information as you can from the client and let the server push the update. There was someone who had a brilliant idea that lead me down this path. I want to say Kayen? Anyway, he basically hid certain spell data so the client didn't parse it's effects. I don't know if a tool has been created yet to ease this process. (It should, it's brilliant and more servers should utilize it!)

I was also able to hide meditate and base values from the client. Once that was done, I was able to comfortably watch a fairly accurate health and mana bar. I never looked into Iksar and Troll regen values but I'd assume those are hard coded.
