What an excellent topic! I completely agree and this has been happening more and more over the years. The new generation of pencilers don't seem to have the ability (or choose not to) depict "story telling" the way this medium really needs. There are two reasons for this from what I can tell:
First I think they are busy trying to be different with competition in the industry so high they feel forced to continue to push the envelope but I think in the end we the readers get the short end of the stick. There are some illustrators I see that have actually made me stop buying titles because I'd sit there saying "my god this is horrible how can they print this?" or "this fight scene is basically a mess."
Second I think there is an effort by the publishers to pander to a new generation of consumers where fast paced cut scenes are expected, because anything that resembles linear story telling is regarded as old fashioned or a bore. Think of the new action sequences in film these days the edits are so close together that you can't even see what is happening. All of these people could learn a thing or two by rereading some Kirby, Ditko, Kane and Adams classics!
I noticed that latey fight scenes are confusing, hard to follow, and story free too. the "team battles as one on one with assists" way of doing things allowed story to flow from it and a sense of danger to appear. This new method is a confused mess i find hard to follow. Marvels penchant for darker and drabber art, color wise since CW makes this even worse.
I have literally read fights in the more recent comics and had no idea who got injured or stopped and how.
