he addressed the subject and gave an interpretation of the rule. The only problem was, he gave an interpretation that contradicted the text without specifically stating that the text was wrong. The text of the ELH indeed says that you can take epic level feats as bonus feats when adding a second class once you've exceeded 20th level. Andy Collins said that the rule should be interpreted that you have to take your bonus feats for your second class from the non-epic bonus feat list. However, this isn't patantly NOT what the rules styate, and, although I and others on the Wizard's message board asked for someone with authority to specifically state that the rule is written wrong, nobody did.
As far as it goes, for the majority of people in the world, who didn't read that thread on the WOTC website, the book reads that you can take epic feats for your bonus feats in your second class provided that your total character level is 21 or more.
