Well the arcane archer is truly nerfed despite everything I've heard to the contrary. They have lost the prestige class ablility to summon anything greater than +1 returning arrows. I don't care that you get improvements to the bows you use now or that you can get bows with +5 or greater on them, it's the principle of the matter that you have removed this core ability from the class that is wrong. If as you are saying that we don't need anything greater than +1 arrows, then all +2 and greater arrows and bolts should be removed from vendors especially from House Deneith patron vendor as they are no longer necessary. Think of all the money players could save by buying ordinary or masterwork arrows only. Of course they would need way more quivers to carry all these arrows around now and therefore would have less pack space for loot from quests but obviously someone thought this would be a good tradeoff for the arcane archer. Next on the list to lose their ability to summon better than +1 ammo will be the artificer, after all they can get crossbows with +5 or greater on them, so they don't need +2 or greater ammo either.
Simply put bring back the Arcane Archer's ability to summon arrows greater than +1, in other words the +2 to +5 arrows as is their right and leave the poor artificers alone also.
