Down with the +X Items!
Without it you will have:
-) more balance
-) less math
-) all items must have interesting features
-) you will need far less items (at the moment Heroes look like Chrismas-Trees), you could even play a non-magic Item Campaign
Monte isn't talking about getting rid of +X items. He is talking more about getting rid of Wealth by Level guidelines.
First, I must admit that I don't have mastery of all the details of the 3//4e rules but ...He is talking more about getting rid of Wealth by Level guidelines.
If character/party CR was derived from the actual bonuses of the character rather than on an assumption of them then monster CR could be pitched relative top that independent of party level.
They have to get rid of the +X Items when the magic Items should no longer be Part of the Leveling-Math or at least have it much lower so it does not make so much difference. An alternative could be that they still have the usual +X Items, but it does not add to the attack bonus (only damage or other modifiers).
