Excellent guide. At level 25, I just respeced out all of my offense, since I wasn't using it anyway.
Some more tips to having a healer, especially a more "full-time" type.
Keep an inspiration slot open. I've got zero use for yellows and reds, and only occasionally need greens or purples. As I result, when there's nobody to heal, I run around handing out candy. In this context, I'm basically a mini-buffer. I'm not saying you should delete an inspiration, or clear out a whole row, but you might use them more frequently that you normally would. Sure, it's only a few minions, but why not pop a red and take them out that much quicker? Between the two of us, we'll probably come up with another one before that big boss fight. Better for a scrapper to "waste" a yellow taking out some weak enemies, than have me delete it because I need more room for Catch a Breath.
Which lead me to blues. For a healer, endurance is the key to keeping you out of debt. I know it's critical to every AT, but not every AT gets yelled at when people die. If you've got extra blues, give them to the healer. If you see the empath's blue bar drop especially low, I'd give them a blue even if it's your only inspiration. A full-charged healer can keep a blaster alive long enough to recover END but, without effective healing, a blaster with full endurance can still be cut down pretty quickly. The upside of giving a blue to a healer is that it puts you in range for a quick HA, so it's like getting a green in exchange for your trouble. Sure, I've got six SOs in RA and Hasten, but there's never been a time when I thought, "You know what, I wish I had less endurance!"
Third, realize that, in a particularly heated battle, a lot of healers aren't even looking at the screen. We're locked on that team status window, racing to keep those little bars from dropping. As a result, we often have trouble seeing when someone is hit by a status effect, which is a problem since we're the ones who are supposed to clear your mind. (I realize we can monitor your buffs/debuffs, and I do my best, but in the melee it's sometimes hard to tell which is which, especially when those red bars are still dropping). I tell my teammates to get acquainted with their F8 key (which calls for help unless you've rebound it to something). In battle, that's my signal to fire off a CM at whoever whistled (not every healer adopts this policy, so you might want to tell them that you'll be calling for help if you get blitzed).
