Why?

I have some questions for Riot, if anyone in the comments believes they can answer them, I would also like to hear since Riot may not be able to answer my questions.

1. Why does , a late game hyper-carry, have so much damage early, to the point he can 1v1 many chamions and win even with a health disadvantage?
2. Why does , have his cooldown reduced on Q with points in the ability, allowing him to instant shove the wave and freely harrass anyone in the wave, or remotely near the wave, such that he can stand in it, and no one can challenge him, but also does not draw aggro? Why does Rumble, a champion who freely pushes out the wave have a massive slow on his harpoon, with barely any cooldown because of charges, that makes it impossible to run at him in lane during his miniscule windows, and makes ganking him not an option either? Why does rumble have a sheild and a movement speed buff to make him even safer in both lane, and all ins, and prevents him from being burst out.
3. Why does have a massive utility ult, that sets up for serious engage when combined with her mobility, and a massive stun range, so that come late game she can be a serious dive threat, and does not have the same kiting and range concerns as Darius and Renekton, but is permitted an incredibly strong early game, complete with ranged CC, a 0 cooldown dash, waveclear, powerful all in, and a damage reduction.
4. Why does , a powerful laner with decent pushing power and ability to harrass in the wave then get out because of movement speed buffs after landing ability, also have the ability to avoid many ganks, and force the enemy to open themselves up heavily to counterganks, or collapses, because they must dive her?
5. Why does , a champion with incredible diving potential, and a guaranteed free early lane, also have the engage range, mobility, CC, and disruption needed to be highly effective in the late game, and compensate for all the normal difficulties of bruiser type champions, such as limited access to targets, huge item differences between damage and durability, and general innability to contribute to the team fight?
6. Why does , a champion with massive scaling, and terrifying pressence in both the team fight, and the trading that comes before, have such a safe laning phase, with what amounts to a spare flash on an 18 second cooldown at first rank, and around 10 (before CDR) at later ranks, in addition to already playing at a massive range because of the low cost and cooldown of Mystic Shot, this "skill shot" eventually is on a less than 1.5 second cooldown, despite more than doubling his effectivness with AD, and allowing him to opt into more utility based items when compared to his other physical damage carries.
7. Why does A champion with incredibly potent engage which is nearly impossible to miss, and quite heavily chunks out squishy characters, due to it being magic damage, with high base numbers, also get to be totally untouhable in lane, not suffering the typical downside over playmaking supports, such as lack of sheilds or heals, lack of escape tools, lack of sustain, long cooldowns, with large windows for abuse, lack of poke, lack of disengage which are present in champions such as but all of which are present in Rakan's kit in addition to the standard benefits of such characters?
8. Why does , a champion with incredible scaling, and raw damage, with burst and execution levels rivaling that of also have access to so much utility, such as being able to utilize on hit's effectively, invisibility, sheilds, movement speed, healing from ability damage on passive, and branking into both AD or AP options for a flexible or even hybridized damage pool?

Just a few simple questions for the Riot live design team, maybe there is something I don't understand about why this game is secretly fun, but if there is, I'd love for someone to bring me up to speed. My biggest question with all of this, is when is Riot going to realize that giving champios everything, doesn't make them interesting, it makes the unbalancable, and it ruins the game
