In PvE, I felt like the recharge rate was perfect, I was getting it every couple minutes in case there's a big fight that I need it in. In PvP, I think the recharge is also fine since the better you perform, the better you're rewarded. Waiting till the very end of the match for your super is actually fun, since in a situation in which I was in last night, where we were down 72-74, I popped my Dawnblade and clutched the victory. I feel like having constant supers in Crucible would be a pain since they can change the game in so many ways.
