clarity on passives under the game info>champions> x champion section

(not sure what board this should go on) i've noticed a lack of info on passives (scaling, base numbers, etc.) on the champion pages. Would it be a pain for Riot to add this information? It'd be nice to know exactly how a passive works before jumping into a game as said champion. For example, Vi getting a shield when her abilities connect with enemies sounds good. The scaling of said shield and the cooldown between shields is not mentioned. I feel like it'd be more convenient for the players if this info was on the LoL site and/or in the champion descriptions in the store/lobby instead of having to look at the description in game or get the scaling info from 3rd party sites. Assuming this wouldn't be a huge pain for Riot, should clarity be added on passive info (and while we're at it, cooldowns to the QWER abilities)?
