Oops. I suppose I should have explained my issue with it more. I don't have a problem at all with the skill vs. defense issue. Use the Force, unfortunately, is different from every other skill in that it encompasses a plethora of powers and abilities.
Where the revised edition made every Force power a separate skill, which was ridiculous, unfortunately the saga edition oversimplified the Force and stuck everything in one skill.
It's only my personal opinion, of course, but to me it's not very fun to have a level one Padawan with a +13 in their Utf. Sure it balances out over a dozen levels but they are essentially incapable of failure in the lower levels. Sure, a pilot can get the same bonus but you don't use the pilot skill to attack or utilize a handful of Force powers.
Oh, how I wish the designers had at least kept the skill divided by the three aspects of the Force: alter, control, and sense. Everything falls pretty handily into those three categories. But I don't care to do that much work for a house rule.
Hence the issue I personally have with the skill. ^_^ I hope that explains it well enough.
