League of Legends (LoL) Question: Why is Inspiration good on riven?

The Domination tree, using Electrocute, is more for a snowballing playstyle. It gives you a lot of burst damage and makes for an easy win in lanes against other top laners who may not be tanky or may not be running Grasp of the Undying. Electrocute falls short of Grasp of the Undying in higher ELO however, due to the proc having a 50sec cooldown early on, whereas Grasp of the Undying can proc every 4 seconds. Basically that means you either only trade 1-2 times every minute, or you lose every trade when you don't have Electrocute. The solution to this problem is the Inspiration tree. Kleptomancy is reliably proc'd by Riven because your trades naturally weave auto attacks in, and your E - Valor gives you a shield so that it's even a safe move to go in, proc klepto once or twice, then get out relatively unscathed. Kleptomancy can let Riven offset tank stats and hp by giving her different potions, elixirs, or even bonus gold so that she can build anti-tank items really quickly. Unsealed Spellbook is great to take on Riven if you're boxbox, or you're just very solid and have very good Riven mechanics and game sense. The reason why is early game you can take Flash and Ignite or Flash and Exhaust to have beter lane control, and then later on you can swap Ignite or whatever you have besides Flash for Teleport so that you can help your team make plays at objectives or to be able to quickly defend a tower from a split pushing champion on the enemy team, or whatever other application you can see for it. It also gives reduced cooldowns to summoner spells, so you can use them more often, causing you to have that potential map presence or 1v1 power more often. In addition, things like Future's Market and Cosmic Insight allow for more Cooldown Reduction than normal and the ability to build items sooner. I hope this helps answer your questions. :)

the big question should be: Why is it not? ofc the answer to this would be it is, which makes me wounder if its not really is to do and be good. Like hey? wtf is even good? and 2, im not high im only drunk.. dont mind me. <3 from me...
