Something else that's worth mention in regards to charges is that, charges on actions with long cooldowns suffer more from the store-and-dump mentality. Take Sage's Phlegma, for example. A 40 second cooldown means you only actually get one instance of Phlegma between each burst window, because two of the three charges you'll generate between each burst window are to be saved for the next. One of the things I keep pitching for Sage is reducing the cooldown of Phlegma from 40 seconds to 20 seconds, and that actually can do a lot of good for the store-and-dump situation as well, because between one burst and the next, you'll generate six Phelgmas instead of three, and now suddenly you go from Phlegma being almost exclusively a burst window button to now something you're using more often than you do during that burst, because you now have four Phlegmas that you can use instead of only one, and I personally think that also makes the store-and-dump mentality feel better as well.
