***** the Cleric Merc just go solo. It takes a bit more time but you certainly learn how to play the toon. I have never grouped since lvl 20+ and have never used a pet or merc and any Ranger on a mount is a Ars**ole. I am on my way to level 100 all solo. Use guile, technique and remember in this game there is no hurry. Enjoy and play the game as it was first intended.
Good luck.
