My players are around 12th level (playing since the introduction of 3E) and I get the feeling that if I tossed in a +3 weapon they could care less, they would much rather have a +1 Keen Flaming Burst or something like that, because they have greater magical weapon, and it only seems like it's going to get worse. When they get to 15th level for the cost of 9,000 gp at most (the cost of a level 3 pearl of power) they can have a +5 weapon 15 hours out of the day. So at that point every melee combatant is walking around with one, damage resistance is moot. Am I missing something?
And yes I know it's vunerable to a dispel magic, but how often can I do that before it becomes tired?
It mostly seems to be a market issue and maybe I'm being overly anal, but why would a paladin, adventuring with a wizard, pay 128,000 gp to go from a +1 keen, lawful, flaming burst longsword to a +5 keen, lawful, flaming burst, longsword when for 9,000 he can have one for the whole time he's awake?
