New Player. Hi :)

Hello I'm Mr Bears. I'm new to the game! I am currently starting with a Druid character named Fox Mccloud. I hope to make some friends here! I have a few questions for anyone who is down to take the time to answer - 1. What's the level cap? 2. What's the strongest class in the game/what are each classes strengths/weaknesses. 3. where do I go to look for good ability builds? <3
