Do ATAs count towards the point value that the 10% of feats allowed?

IE...
250 points of characters
20 points of ATA
=270 points

Can I use 27 points of feats, or 25? Or have I been out the game so long that the 10% is now calculated on the total build allowance?

The 10% cap has always been based on the build total. So in a 300 point game it would be 30 points of feats.

From p. 19 of the Blackest Night Rulebook:

ATAs are not feats, so the are unaffected by the 10% rule.
And the 10% is of the build total, so you would be able to add 30 points of feats, assuming it is a 300 point build.

Awesome to read this thread- I was trying to figure out how to do a good 500pt Thunderbolts team, but couldn't figure out how adding the ATA worked into the mix with the new rules and whatnot.

Kudos and thanks to everyone who contributed!
