So i don't think that making more than bunch of clones is possibly for casual and most of the great ninjas. Naruto could because he used kyuubi chakra and thats the only reason. I would not like to see people with like 100 clones because they found a scroll, scroll doesn't increase your chakra level. If its possible it would be cool to - as you master jutsu - give your clones commands. In wow you had a pet bar, something like that could be awesome too - they work as AI but, you can put something on a bar and clone might have chance of using it. This kind of actions would make game harder and more tactical, or dunno...in a fight there would be a chance that quick time event will occur(you know one of your clones have a chance of using one of know jutsus and you must do some combination to work with him) could be also cool.
