When I was a kid, my mom used to say that she had to walk uphill both ways to get to and from her elementary school. Since we lived in a really flat area (and she grew up somewhere on the other side of the state), I really didn’t understand what she meant until I was older and actually looked at the “hill” she walked up and down. It was more like 2 hills (where her home was on one of the hills, and her school was on the other). To get to school, she walked down one of the hills & came back up the other (and it’s pretty steep).
What does this have to do with leveling resto? Mostly, because I feel that leveling full resto is like walking to level 80 uphill both ways… when it would be easier if you could just get in a car and drive there (but my mom couldn’t drive back then, since she was just a kid & walking alone was still safe). Similarly, when I was a young WoW player, I had to level resto, because druids didn’t have access to faster leveling specs back then. I also never killed anything solo (as in I pretty much healed my way to 80 – I had RL friends, and random strangers I made friends with just so I wouldn’t have to level alone).
Now that feral and balance are BOTH good for leveling at a fairly efficient speed, I personally recommend that you pick the fast & easier way to level. You can pick from either feral (sports car – fast & flashy) or balance (sedan – not quite as flashy, but still gets the job done in a reasonable amount of time). Doesn’t matter which kind of car you want to drive; if you really like casting, then go balance.
The original point of starting this post was to plug another blog. I ran across a post on The Druid Team blog about leveling as restoration, where someone actually did level resto more recently. That post concludes that it’s slow & you should do it with friends if you do decide to do it.
However, if you think about my walking (resto) vs. driving (feral or balance) up the (leveling) hill analogy… I personally recommend that you don’t do it the hard way.
