The changes in the workflow options took me by surprise too.
The image size choices that used to be offered when the image pixel dimensions allowed for enlarging or reducing the image were instantly understandable. Now it takes a short period of thinking to figure out the possibilities. Not a biggie.
I'm sure I'll adapt after some experimentation.
Yes, the crop tool is now decoupled from the image size settings. The revised image size settings are more similar to the ones found in the Lr Export dialog, where you can choose specific resize metrics (e.g., want the long side to be a specific size, like 1024 pixels).
I'm in the process of going through 1100+ images from a recent vacation, selecting and re-sizing for transfer to an iPad. Actually the new arrangement is working out ok, I'm adjusting and cropping on the originals, then going back and doing a multiple save out at the desired resolution. Most of my images are un-cropped, so this new configuration saves a lot of full frame cropping.
As long as I remember to disable the resize before moving images to Photoshop all is ok, even preferable. Sorry I complained, nothing like using a tool to understand the pros and cons.
You could go through the 1100 images and make the changes you want using ACR and then from within Bridge use the Image Processor to reduce the size of all the images at one time.
In Bridge, Tools --> Photoshop --> Image Processor... (at least that's where it is in CS6)
It might be easier than doing them one at a time.
Give me credit, I'm not doing them "one at a time", I'm batching a group within ACR.
