I use Reverb rarely, but when a track calls for it, there is nothing else to have the effect (maybe ambience restoration might work...).
Using reverb to fix clipped endings of songs gets used maybe every 5th session or so; just to repair a "damaged" source, an ending that is cut too short and thus sounds unnatural.
Using reverb on a track to smooth it out or to give it ambience is used pretty rarely here. Usual occasions may be balads that sound too direct or single tracks that are much more direct sounding than all others on an album. This is pretty rare though - happens here maybe every 2 months or so and will always be run by the client first. Last time I used reverb on a whole track was 2 months ago on a softer song of a rock album that just seemed to lack dimension compared to the other tracks and with regards to its mood. The little bit of reverb worked wonders - suddenly it slotted in nicely in the album where before, it would stand out in a slightly irritating way.
I should say though that reverb for that purpose is applied very, very carefully and is usually added in amounts that as close to unnoticeably as possible while still achieving the desired effect.
