To be a great player and supporter. I don't expect to get to a professional level, but want to learn and be a better player with a group of people who care.
I played a LOT of Dota in WC3. I played quite a bit of Dota 2 when it originally launched, but then fell off the wagon to traditional MMORPG games. I played a lot of League of Legends with Silver/Gold players on my team, but got stuck in ELO hell in solo games.
I enjoy support roles the most but have found that in solo queue if you have a rage quit carry or someone who stops caring, you don't have as much pull to carry in a game if you are a support...as the name implies.
My favorite supports are Winter Wyvern, Dazzle and Omniknight.
