My friend said flurry and ew are now a legal move is this true

It is not true. Flurry and Exploit Weakness are both Close Combat Actions, so you would have to pick one or the other.

I thought it was Power Actions that could not be combined, not Combat Actions. I remember reading in the rule book that you can't use more than one Power Action per character per turn, but you could use a Power Action and Combat Action together, or multiple Combat Actions.... I must have been wrong. Would anyone care to explain this all in better detail for me? That way I can tell my roommates about this and implement it into our next gaming session.

It's not just power actions--each action you give to a character to activate a power is used for that particular power. If you give a character a close combat action to activate exploit weakness, you can't give him another one to use flurry.

Blades/claws/fangs is an exception to the normal wording and works with other powers because instead of starting with "Give this character a close combat action" it says "When this character is given a close combat action" meaning that it triggers when you give a close combat action for something else.
If either exploit weakness or flurry was worded the same was as blades/claws/fangs, you could use exploit weakness and flurry together, but that's not how they're actually written.

I really recommend reading the post stickied in this forum called "explaining power interactions." It does a great job of explaining why some things work together and others don't.

Thanks a bunch. That was super helpful. This site has never let me down, everyone on it has been more than awesome.
