I got to play the guardian themed cleric and was very disappointed. While the ability to give disadvantage is a good ability, the fact that, as the defender, I had no way of stopping enemies from "dancing around in my threat range". The enemies just walked around me and got into a position so that I couldn't do anything. Attacks of opportunity and marking were amazing ways to make sure this didn't happen. What is the point of playing a defender when u can't defend your allies. I absolutely hate that the fighter just has basic attacks and the wizard gets to cast spells at will (cantrips seem to be pretty power full. Magic missile always hits and deals OK damage, uses no ammunition, and has a good range.) Also don't like to hit rolls don't increase at lvl 3. I think this system needs a little more 4th edition rules to solidify it's rules. Giving a wizard a wand would make more sense than magic missile at will.
