Deciding on what to play

[Tacitus]

.ive been on this server for a couple weeks and i love it im glad i found it. It completely touches my heart to be playing the game i grew up with. I started a wizard and hns level 24. I want to make a new character and i bought gear for a priest yet i dont know which one to roll between a cleric, shaman, or druid. I tried looking at player guides on the wiki but simply cant be convinced to pick one. Im looking for a good main, something usefull, can solo and be good in groups....but also something i wont get bored with in 15 levels. Would appreciate if someone gave me some opinions.
