The main issue for me here, was to know if the client tries to calculate anything, such as chance to hit. The reason for this (asking) would of course be to know if one can simply find things such as equations for how damage, armor and such things work. An other example, that doesn't even require random numbers, is mana regeneration, it could be handled client side, with just updating from the server every now and then to see one is in synch (obviously it is always the server mana that is checkd to see if you can really do a spell). Again, if it did, one could find exact formulas and so on.
So, basicaly, my question was not what the server do and what the client do. I assume the server do everything, but wonder what possible parts the client predict or do itself so that one can find formulas. One other example would be the values shown on the UI for example for DPS. Is that a value calculated by the server and sent to the client? Or do the client simply send char stats such as int, dex, str and modifiers on items and have the client calculate the DPS value? That would mean one can find formulas for things Blizzard doesn't seem to give away. Things that really won't lend anyone to be able to cheat, yet lessen some work from the servers. Of course, Blizzard can simply have chosen to not do ANYTHING on the client, just to be sure. Considering Blizzard have never liked to tell how things really work under the hood and have people guess, I would not be surprised.

There are three types of people in the world. Those who can count and those who can't.
