Deset Gled said:Which puts the spotlight on my opinion of the MIC: It's pure power creep (with a side of rules bloat). Everything becomes more powerful. You'll still be balanced as long as everyone uses it. This isn't necessarily bad, but it is something you need to be aware of, plan for, and make sure everyone is happy with it.
I do find it kind of entertaining that WotC released the MIC, and then later released design articles talking about characters being a walking X-mas tree of magic items. Sure, this was a general problem with 3.x in general, but in this analogy the MIC is kind of like those Hallmark ornaments that light up and play music.
I think that's a rather unfair observation. As I understand it, the Christmas Tree analogy, in addition to being a rather poor analogy, was aimed more at the Big Six that you had to have in order to survive rather than a collection of magic items that gave you cool, but not particularly powerful abilities. If you took a look at the standard adventurer pre-MIC, I'd wager that he had spent on average 90% of his wealth on Big Six items. The problem is that the Big Six are obscenely boring; they don't let you do anything new, they just make you slightly better at what you always do.
The purpose of the MIC is to give the players a large collection of fun, cheap alternatives to the Big Six, which are close in power, but require more thought, than Big Six items. WotC realized that sticking to the formulas in the book resulted in 95% of the published magic items never seeing the light of day, so they made a book full of magic items that were intended to be used.
