fastlane69 is right. I spent months doing something with A6. When A7 came out, alot of the stuff I had wasted my time doing was being already done for me. But hey, everyone is different. You might be a C guru. It's the age old battle: time vs money. A7 is much better for MP.

With A6 I did what your doing... create an entity on the client side, and simply sent information to that entity always using a string (personally I think it's not to bad for some of the simply things you might do early on, but it's not very effective for many other things you might wanna do later).
