First of all, I'm going to take the high road by not discussing your hypocrisy when you say "no flaming" and to be "mature", then proceed to insult all Riven players by stating all they do is mash their keyboard.
More on topic; no. Giving her more energy creates more problems than it solves.
There was already another thread on this earlier where I explained my thoughts behind my reasoning.
To recapitulate it, Riven's role is that of an assassin in teamfights. She wants to jump the backline much like Zed, Talon and Fizz. However, she lacks the blinks/ invulnerability of the other assassins, meaning she's less safe while being just as squishy, which means her shield is essential to letting her do her job. She needs to be able absorb a spell or a couple of AAs.
Not only that, but it would make her fairly immobile (i.e. as far as useful mobility). By that I mean she has to blow 3 spells on average to reach teamfights (taking her Q-Q-E-R-Q-Hydra-W animation cancel for example) which means by the time she enters the fight, she'd already be out of energy.
She's already fairly easy to deal with in lane if you know how to play around her. She's a lane bully, she's meant to be obnoxious. She needs to be, otherwise we'd see an abundance of dominant mid and late game carries. Not to mention, her entire kit is interactive. It's literally bursting with counterplay.
Edit: 15 hours of studying makes me bad at grammar
