Please, please bring back the original clarity slider...the one in Lightroom 4 is dreadful. It adds exposure adjustments now and is difficult to control. The subtlety of the older version is gone...if anyone else agrees with me then please comment below and perhaps Adobe will take notice.
I have read someone from Adobe say something similar to "The new clarity slider has twice the effect as the old one".
So, if you were using a clarity of 25 in the past, maybe you should try a 12. Or maybe you should continue to use Process Version 2010, which still has the old clarity slider
Do you really think Adobe will go back just because some people in a forum don't like it?
For what its worth, I like the new clarity slider, I think it is an improvement.
There is more to it than just the strength of the clarity slider in LR4 - see here: http://www.keptlight.com/2012/04/lightroom-4-clarity-slider/
I use the clarity slider in negative as a quick fix for smoothing skin. In LR4 this is noit possible as it changes the exposure substantially.
And yes - if enough people complain about it perhaps Adobe will do something about it.
