It's one of the most useful solo skills a rogue has, and in groups without a mage, it's very valuable. Improved sap is a great thing.
Once you're raiding it becomes a lot less significant, sure. But my rogue alt is going to be heavy subtlety for a long time - it's incredible amounts of fun.
Full points it's 90%. If you don't step on someone's toe, you will almost always succeed, and if you don't, you vanish (which is fine, because you're the only person in combat) and try it again. If you have Preparation, you can even try it a THIRD time.
I don't remember the other skills higher in the tree, but I had no problem picking them. The one that adds effective levels to your stealth is very nice - at 36 I can wander around 40s without much worry, which is great for herb picking.
As noted, sap is VERY useful for a soloer. You can easily take out groups of three by sapping one and popping evasion - I do it all the time. Lots of stuns to let your energy fill back up is critical too, so improve those.
Well, part of the reason is precisely to get cash so you can afford to buy better equipment. Rogues are VERY gear dependent. * -- * PV something like badgers--something like lizards--and something like corkscrews.
