One of the decisions you'll want to consider around getting your first combat skill to level 50 is if you are interested in all the benefits that come with being a Druid. Druid's combat skill is considerably powerful and comes with a lot of versatility, Druid works with a lot of animal forms, and the Druid travel options are considerably powerful.

The main drawback is also pretty light in some respects. You cannot get XP in anything other than Druid while a Druid event is taking place. This originally seemed like it would be a pretty big drawback, but considering the benefits and the fact there always seems to be Druids online to clear mobs, I don't think you hear many Druids complaining about it.
