Now is the perfect time to work on that alt you've been keeping locked away, sad and lonely for so long in his little alt box. You've got time now, right? Deathwing is long dead, and things are pretty chill. I even heard there's a new island out there to explore one of these days, most hopefully in July or August, which would be pretty cool.
Ironically, when I'm leveling most of my alts from an early level, I don't enable most of my addons. What's the point? Group and raid content that requires any addons is far off in the future, the number of abilities I have at the time doesn't reflect the button matrices that I've built for level 85, and there is practically no similarity to playstyle. So I turn off my addons, save some very crucial ones.
If you're looking to go addon-light for your next alt, I've got some addons that you're going to want to keep around because they make your life a thousand times easier. WoW's UI has gotten a lot better in recent years, but it still isn't perfect. These addons bring it a little closer to that perfection.
