Prior to me taking a break from WOW, I had a level 85 Druid hanging around as my Bank alt. She did inscription so would sit in Stormwind making and selling Glyphs. I decided to level her to 90 which I finally achieved this past Sunday. My Druid was my main during Cataclysm; it was during that time I made my most amount of Gold from the Auction House.
Going into a battleground as a fresh 90 with Crafted gear is a rude awakening at best. Thank goodness for stealth and the Night Elf racial of Shadow meld, gets me out of trouble a lot.
I originally levelled my Druid as a Tauren Tank just to get instant Queues for 5 mans. Also most of my friends were Horde at the time.
My next character to 90 will either be my Monk or Shaman, I’m leaning towards the Shaman but time will tell. People probably think that I’m crazy to have so many alts; I find it almost easier to level a character than to gear one out. Also I get bored easily and need something new to play with.
What it really helps with is understanding what other classes do so that I’m better able to play against them in PvP.
