What do you mean? Granted I am not following super closely every avengers team with thor in it, but Thor in recent history, beat down extremis iron man easily and told stark off in a great issue, highly recomend it, Thor Vol 2, #4 by Strat. thor kills the sentry in siege (it's very strongly implied that the Sentry's human side, Bob Reynolds, willed himself to die and that Thor was just the instrument he used to bring about his own death), defeats angrir and the serpent in FI (and dies in the process), is able to hurt the pheonix in space (before the Phoenix then kicks his ass multiple times, followed closely by Emma Frost). I will admit that certain writers treat Thor like crap and that needs to change, but on the whole Thor's stength is respected.
