I think I'm going to try for a completionist in 2015, starting in January and hopefully finishing in December. The primary concept I'm going for is playing each class as a pure build. For non-self-healing builds like barbarian or fighter I'll probably stock up on silver flame pots.
Combining such a large number of builds with my general obsessiveness about planning ahead, it will be easier for me to keep track of everything in a single thread instead of a ton of spreashsheets. This seemed like the most appropriate place to put everything.
