1. I stacked Agility on my Warrior because I thought it made you more efficient at running/jumping
2. On my Troll Hunter I got up to level 55 (wearing all Cloth/Leather armor because I didn't think stats were important, and it looked cool...also I would not use spells, only mash the T key because I thought that's how you shot arrows) Also I thought The Barrens and Durotar made up te whole continent of Kalimdor. THey were shaped similarly and I could not read maps ok?!
3. Made a Troll DK and wore Intel gear because it looked cool and matched my other plate. It was only until level 72 or so during a run through Utgarde Keep that this douchebag pally told me how I was stupid for "stealing" his blue intel chestpiece and yadda yadda so then I started paying attention to stats. Sadly there was no transmog back then so I ended up selling all the matching sets I had made.
