I've seen this mentioned a few times in the thread here that a bard may have the same wand/scroll ability as a rogue or rogue splash build that has UMD. I'm hard-pressed to think of a build where this should ever be the case. A single level of bard and a single enhancement point spent gives you a 30% bonus to all wands and scrolls. That's a significant increase in healing and may mean the difference when running ToD between being able to scroll heal or not being able to scroll heal - especially if your target is a healing amp based build where instead of increasing your heal scroll from 110 to 143 you're increasing it (in the case of my current toon at level 17+) from 449 to 583. And that's at the first tier of Wand & Scroll Mastery. The top tier would actually be overkill for my build but a more reasonable 300% healing amp you'd be looking at going from a 330 heal (probably not going to work for solo scrolling the tank) to 577 heal (would almost certainly work with spot-healing thrown in).
So while I can understand not being able to spring for the 9ap's to get a 34.6% increase (1.3x to 1.75x) in wand and scroll effectiveness I have a hard time understanding any bard build not spending 1ap to get a 30% increase. It's extremely cheap and that 1ap is almost as much of an increase as the next 9 provide. Being better than the rogue/rogue-splashes in a pinch should be as common in bard builds as Toughness should be in all builds. How much better is certainly up to build choices but I can't imagine completely eschewing the Wand & Scroll line.
