Alright, maybe for a level 80 it isn't the most difficult task to complete, but before going for the achievement I had only been to maybe half of the instances the original game had to offer, but now I have seen them all, and I think I can understand why people are so drawn to it.
My first character I got to level 60 was my rogue, and this was before the first expansion, so I had a chance to run a few of the end game instances. My experience with it wasn't too great. Being a rogue it was very difficult to find a group, as there was never a shortage of DPS characters needing groups.
Now I get to see them in sort of a different light. Sure I can blow through them really quick on my own, but trying to think about what it would be like for a group of level 60's trying to make their way through one of those instances makes it very interesting.
I'm able to skip so many mobs, the loot doesn't matter, and the bosses go down easily for me. An instance like BRD was just so big, I can't imagine working my way through it at that level. I really can see why instances have become more and more streamlined starting with the first expansion. They were big and epic before, but just took too much time for me to want to run through them constantly.
Next up, time to get my hunter ready to solo Heroic Underbog, or get a better attempt in at least. She'll be questing in the Storm Peaks first, then moving on to Icecrown if her turtle pet hasn't hit 80 by then. The new patch just decreased the amount of experience for a pet to gain a level too, so this should go more quickly than it was.
Besides that, I plan on taking my druid to the new Heroic instances with my guild, and hopefully get some crazy gear out of it. Blackbare has really become my instance guy, and the funny part is that since we have such a good tank in the guild that leads us through, I end up running everything in cat form as DPS. Not really what I expected his role to be, but hopefully I can eventually get an off-spec set and go boomkin as my dual spec. Oh that would be sweet. I wouldn't mind trying healing either at some point.
