I hit 50 by accident last night and OMG was I bombarded with new things. While my head was spinning trying to make sense of the metric ton of content like Planar Levels and Prestige Levels (both cool ideas btw), my quest log was steadily reaching capacity. As I wanted to go to a new zone and not be limited, I looked at ways to clear out my log.
My first mistake was not PvPing more in order to get the PvP quests all completed BEFORE 50. (And another mistake was not PvPing more so that I had more Favor to spend on instant PvP Gear upgrades at 50)
My second mistake was ignoring dungeons as I leveled. So my question now is, what is my best option for solo'ing low-level dungeons as a Mage? I am assuming going with a Stormcaller-based build would be the best for clearing trash quickly. I don't really care about getting XP by mentoring in the dungeons, so I would run these at 50. I just want to complete the quest (completionist) and see the content at least once.
