Sounds like your little birdy bent GC's words a little bit.
I could be wrong, of course, but last I heard they simply said they "don't like" on-next-swing attacks but aren't sure what they're going to do with them.
To the OP, the answer is yes, same for all classes on next attack abilities, they are flawed from a design stand point. if they did a shit ton of damaged, on next attacks could be justified. they will be changing, all of them not just on Warriors.
