Shrinivas,
Depending on your specialty, it can be common that the clients themselves don't really know what they need. I include a set series of questions in every proposal I make, which might overwhelm some clients (the ones I would likely not want to work with anyway) but often results in summary or detailed responses from potential clients and the beginning of a useful dialogue.
But if a freelancer's average project is usually low-priced or they have a low response rate on their proposals, it's now very expensive (too expensive?) to spend money on all the connects need to make a large number of proposals that ask alot of questions. Which is why Upwork thinks the substantial increase in the price of connects will reduce the number of average proposals submitted on many new projects.
