Note that the self-silence lasts for a constant of around 1.3 seconds per shield, so at the very worst you'll CC yourself for 2.6 seconds. This is better than Varus, who cannot use abilities or even attack while charging his (which also slows him down), and, who's rooted for up to 8 seconds with his. There is also a valid tradeoff: if you silence yourself now, you'll have a chance to slow down multiple enemy teammates (or, even better, taunt them) twice.
