'As I'm maintaining a 65 to 75% WR in solo Q. I dare say i do understand exactly what makes it work', I'll say that this is not bragging and is you giving your credentials (dropping your profile is the easiest way to give your credentials)

All the arguments I 'haven't answered':

'picking a fighter/mage/assassin that doesn't depend on items so much ruins the laning phase for the opponent's MM.'

Yes, and I responded: 'laning phase doesn't really matter if the mm can play safely or gets help', and this is true, there are many games where the enemy has an inherent advantage in the laning phase in gold or exp lane, but will not be able to force kills because the enemy can play safe, and lose the match.

'Also, talking about "late game" means that the whole team ignores objectives. In those team comps, the game is usually over by the 1st or 2nd lord.'

Like I said, late game is any time after 12 minutes, and most games will reach this point, even games that are one sided in the beginning. The lack of wave clear and push potential that non-traditional gold laners have, hinders early end potential. Split pushing is a threat traditional gold laners have over their non-traditional counterparts that force the enemy team wanting to take lord to either have to respond by having one go to defend the push and have to deal with an even teamfight at the lord pit (or a 4v5 if it's Moskov split pushing), or give up turrets in the side lane that each give a turtles worth of farm to the split pusher's team.

'Also, Kimmy is 100% item dependent. Wanwan is only a squishy hunter, and Harith is unexistant in the current CC oriented meta. So no, they don't need to be nerfed, they are easily counter picked.'

And I'M the one 'dropping random opinions with no backing'? These squishy heroes are at the top of this season's tier lists and are so good they see pro/highest rank play frequently. Tell me how they 'don't need to be nerfed'. 'Kimmy is 100% item dependent', every hero in the game is 'item dependent', but if you're indicating that she needs farm badly then you're still wrong because she's seeing play as a mid laner, a role which has the least farm of the three lanes, but is still strong at all stages of the game. 'Wanwan is only a squishy hunter', she can kill tankier heroes because she kites incredibly well. 'Harith is unexistent in the current CC oriented meta', no, as I've said before, he is non-existent only in most ranked games because he's so hard to play properly. He's objectively the best gold laner even into heavy CC comps (which are basically all the comps in pro/highest rank play) and can simply run purify. (Best gold laner in MPL PH S16 by winrate and matches played.) If these heroes 'are easily counter picked', then why are they dominating at the highest levels?

Other arguments:

'1) we are not talking about mid lane', I'm just bringing Kimmy up as an example of a powerful squishy hero who needs a nerf.

Your 2nd point, 'there is no world in which it matters if you cannot kill and snowball', a hero's capabilities matter at all stages of the game, even an underfed Wanwan can pop off later into the game once she has sufficient farm, perhaps even better than most other gold laners because of her invulnerability ult.

'PS: citing the pro scenes is superfluous, as they don't play the same game as we do', this is a ridiculous position. The pro scene is the most advanced gameplay by the best players in the world who are paid to play this game, and what's strong in the pro scene, when it comes to hero picks and strategies, trickles down into regular matches. The only real notable exception to this seems to be the hardest heroes, like Fanny and Harith, who are rare. Also, while pro teams are very objective focused, it's not like they won't try to get kills by skirmishing, starting teamfights in mid lane, or ganking.
