Sometimes, you just need to cool down. That has been the case with me recently when it comes to running Heroics in Cataclysm. I had to take a step away from them so that I would still enjoy playing the game.
The good thing is that this is a fresh expansion and there was plenty of stuff to do. I have been doing a variety of things that have helped me cool off a bit and will give me the motivation to try Heroics again soon.
First thing is Archaeology. So far I have gotten a bunch of crap, but I know that there are treasures out there. One of my friends has already completed five rare ones including a fossil raptor mount and non combat pet. Something that makes a bunch of dwarf chicks with swords dance. A Mechanognome pet and something that makes a shade of himself. It is pretty easy and a nice way to kill some time while you chat on vent with your buddies.
Second thing I have been working on is my professions a bit. I have been doing some work on my Insciption and Jewelcrafting while gathering other materials for my Engineering.
The third thing has been rep grinding. I have been doing Therazane and Wildhammer Dailies to go along with a few regular instances for additional rep and gear. Dailies are quick and easy and make a decent distraction.
The last thing I have been doing is what I have always done. Build a giant pile of gold. I have been selling all kinds of miscellaneous things I have crafted as well as some of the archaeology pieces. I have also been keeping up with my Glyph Making. They are selling at very good prices on my server and I pull in 1.5-3k a day with very minimal work.
Sometimes you just need to see the other things that are enjoyable to you. I will be ready for Heroics again.....soon.
