I've never played a character that focused on CM, such as a Warrior. I'm a little fuzzy on what the general training expectations are:
1) Picking up a rank in a CM skill: is it with the intention of eventually mastering that skill or are there diminishing returns in effect? In other words do you master few skills or pick up a few ranks in many more skills?
2) Mastering a skill: a goal for much later in life or do you strive to achieve mastery as soon as possible once you've started down the path of that skill?
3) Dabbling but not mastering: if I want to be at least competent against like level how many ranks should I aim for (assuming 5 ranks possible)?
4) What are some of the "hands down required" CM skills?
