Not really, no, in answer to your question in the thread title. 10 eyes is the max limit for an agent. Your chance to get a kill can vary widely depending on a number of factors. There are a lot of traits a general can get that influence personal security, making assassination harder. Trying and failing an assassination will make it worse the next time. Now, sometimes you find the opposite. A general can also wind up with those "trusting" traits that makes assassination easier. Also, the size of the army has an effect, as does the presence of enemy assassins/spies in the army. Personally, I like it better this way. While it's very hard to work up an assassin to that level the first time, it's easier to train new ones once you start passing the retinue along to the new guys. Before this change, it was a little too easy to pull off assassinations.
