Don't see any mention of it yet, so I'll add another reminder.
All blaster secondary sets were getting a self heal. For example with /EM, conserve power was being changed to an Energize clone. Along with the snipe and nuke changes, it was going to completely change the blaster AT. I was playing on the Test server a lot around then, and my blaster became truly a completely different character. More damage, and much more survivability.
That's part of the reason the shutdown angered so many. I24 was going to be perhaps the most popular update to date. It was adding so many great things, while ruining nothing. It was the absolute worst time to shut the game down.
