Sure you get quest rewards, you can do dungeons, you gain professions and all that, but in the end, 95% of it is pointless and you can do without. Just spam quests as fast as you can and break through it into greener pastures. Only in Northrend, does it finally start making sense, as the gear and rewards you get begin to not only look good, but also provide a useful function.
Anyway, enough about ranting. Achn has made it to Northrend and the fun has really started. You may have also noticed that he has gone through a serious transformation; not only his name but exterior has been altered. Achn is no more, and instead before us, is Barunn, son of Ironforge. I made the decision for the race change primarily because I wanted the dwarf casting animations, which are way cooler than that of a human. Made me sad to see Achn disappear, but I am still happy with the end result.
So much has changed, but for the better I think. Me and Ylinya, whom have since the beginning, leveled together, have already started our first dungeons, Utgarde Keep and Nexus. So far, everything has gone swell and we are on our way to max level. For me, Northrend has again provided with a play challenge, much like when doing Outland dungeons did. I have reached such spells as Prayer of Mending and Penance, both high end and only now, finally getting to use them, does the class seem to truly come together.
It is a fun experience to go through and I imagine, once heroics become involved, the game will again change to a certain extend. We will see, just how much, one we get that there.
