No, it wouldn't. Why didn't you max Dark Sight in 1st job?
Dropping Drain down to 11 in favor of Endure is a huge waste of SP imo. Endure is good for Bandits because Steal is useless. However, it only gives you 20 extra MP every 10 seconds. This is like 7,200 MP in an hour. You said you're not poor, so why would you care about that kind of savings? Use Drain like 10 times in an hour and you'll save more money than that. Drain isn't only good for saving money, it can be used as a finisher and allow you to carry less pots.
