Did the CE onece - on one character successfully; and unless they revamp it into something WAY less tedious, that'll be it for that FA.
And you know, I do understand the reason they decided to Level-Band FAs in general; but I really wish they'd fnd a way to port the 'Giant Monster' code from Champions Online (you can have plaers across the ENTIRE level range of the game all attack one of the Giant MOBs; and it's able to scale both damage taken and damage done based on player level); beause the majority of the FAs ARE fun when you can get a group of 20 going; but with the Level-Banding, that rarely happens and FAs across the game are vitual ghost towns (and not because people don't want to do them, but everyone ends up in their own banded instance.)
But I really enjoyed a numbver of the FAs during beta - and in the early days of launch, prior to all the level banding.
