there's nothing wrong with certain bruisers being scaling threats
Exactly, Certain bruisers. Renekton/pantheon shouldn't be scaling threats. Due to the natural way their kit works, it's hard for them to become scaling threats, because renekton could late-game oneshot a team if you made it that way, and his early game is powerful because of the different aspects he has that are early-game centric (Q sustain and poke, high mobility and single target burst with W, removing some base dmg doesn't take away he will still have the easier trades in most matchups while scaling would make him obliterate late-game, since he already has great bonus AD scaling if he knows how to combo a team, especially when lvl difference is big) while pantheon naturally has early game dueling due to his passive AA block and single target Q poke, only way to make him scale better late is to rework his passive so that it gives him a duration based AA block much like jax, but then he just becomes a roaming ability focussed version of jax.
And certain other bruisers, like Fiora and Jax already are scaling threats, but they do it in a toxic way (u can't outposition them, or dive them under tower, like u can do with marksmen because of how they have some form of damage/cc mitigation and natural tankiness which melee champs need to function as carry's (even yi needs his alpha and slow immune to become a carry, remove either and u can just garbage can him).
marksman could do with a flat nerf to their late game and nothing else. they are more relevant than they've ever been early game, even the hypercarries like twitch and kogmaw
Both of these can easily be countered in the early game, and can severely be outplayed late. As long as the teams are even, and you didn't counterpick yourself by grabbing nothing to jump onto these threats, you can always try to catch them out allowing for situations where playmaking is opposed by the hypercarry trying to avoid getting caught. The fact u mention supports being able to protect them, is not the issue of hypercarry marksman, because trust me, it's just as toxic on a hypercarry toplaner or even just any fighter or assasin that can deal a certain amount of sustain damage (read: trundle, kled, talon, jayce etc). But supports need to feel like they can be useful, but it's healing/shielding that is the problem, mainly ardent censer and the new healing/shielding power items, because they never really rebalanced enchanters around this.
jungle won't change, ruined king tribute is for tanky fighters not mages.
Ohhh im sorry what? How is this so, why can't an AP jungler opt to go for ruined king tribute if they need it to sustain. I agree with the krugs issue, but krugs generally feels bad on any jungler that can't deal enough AA dmg, including tank junglers, while feeling too easy to take for most toplaners. (the amount of free gold a renekton/riven can get from that while being both ahead and behind is just bull and needs to be changed)
was god tier; i rarely see the classic burst mages anymore
