2 Pallies seemed fun for me. I got them to about level 15 before I decided to start boosting one (since I need a tank desperately).

The trick for me was that my 'main' pally would actually take a step through the mob, and quick turn around to attack it. This meant the 'follower' pally was also in position to attack. I don't see why folks say it's so terrible.
