Nice!
I really liked how "real" Cap's acrobatics felt in TWS. All Whedon did was have him magically levitate over a couple railings and do that one CGI leaping spin kick. None of it seemed like a real guy who was actually capable of those athletic feats.
Cap obviously has more action scenes in TWS, as does every character in their own solo movie vs The Avengers movie. Iron Man has more action in IM, IM2, IM3 individually than he does in The Avengers, Thor in Thor and Thor: TDW, and Cap in TFA and TWS. That is always going to be the case when you have a character that has it's own series but then has to share a movie with 5 other top tier characters.
I think people really do forget the action scenes that Cap has in The Avengers, he has just as much as everybody else;
Showdown with loki in Germany
Showdown with Iron Man and Thor in the forest
Taking out the Loki-hypnotised SHIELD Agents on the Helicarrier (batting the grendade away, knocking one agent out, throwing another over the railing to his death, and then keeping the final guy at bay with the machine gun)
Co-ordinating the NYPD and then beating up 4 Chitauri single handedly to prove his point
In the action montage of BW and HE, Cap comes in and takes down 2 Chitauri shortly before Thor arrives after his fight with Loki and we then have the "Assemble" scene
The spin kick and shield beam combo with Iron Man
Cap takes down 3 Chitauri in the Bank before setting the hostages free
His fight scene against the Chitauri, teaming up with Thor
