I'm one of the slowest levelers you will ever meet, so I'm usually very aware of when I will be hitting my next level. I've usually spent days of play time waiting for it, so it's one of those great feelings. I was particularly looking forward to hearing my first Ding in close to a year, but I missed it!
I was grinding some Mammoth meat in Borean Tundra for cooking, when I accidentally over pulled and had about 4 Mammoths on me with 20% life left. Just as I hit the vanish button I notice I'm at full health and very confused. After 10 minutes of thinking about all the possible explanations I realised I was now level 71 after killing one of the Mammoths, I'd got my full life back. Shows how strange it is to be leveling again. My confusion meant I didn't even get the obligatory and forced "Gz" we all crave. /cry
I better not miss the next nine level ups, but alteast we have Achievement Gratz now.
