Not so daily reminder renekton needs some love

Renekton has very low winrate as the title would suggest. He used to be a measuring stick for if/how other champs could handle top lane laning phase. If you could survive or beat renekton, you could play said champ top; if not, you weren't viable. These days, the majority of champs either straight up win lane vs him and win duels early game, or survive just fine, ignore his "powerful" early game, and outscale him easily by mid game.

Some factors contributing to this include high base damage on tank abilities, long delay before cleaver is completed (without it, tanks often win duels or come close enough that threat of jg intervention makes all-in's extremely risky), many other toplaners making more effective use of most keystones, and buffs to several other toplaners which prevent renekton from being properly allowed to bully early and build the lead he needs to be effective into the mid and late game (without massive outplay or skill difference in favor of the renekton). Because of this, and because the vast majority of toplaners outscale renekton, he has an abysmal winrate. So looking at the issues - he doesn't bully early the way he used to, he doesn't scale well - we can see two areas in which he can be improved.

Some suggestions: Build up fury faster and/or no loss of fury if not in combat (like shyv ult availability)

Stronger empowered abilities (more damage, more armor pen, longer stun duration, and/or more healing) - this can be played around by his opponents, allowing for more fairness to both sides

Longer/scaling stun duration on w - he maxes this last, so this one would let him scale better into the mid/late game; most other champs either get more from their stun, or have longer duration stun and/or scaling duration.

Make ability scaling based off TOTAL AD instead of bonus ad - this means he still has relevant damage mid/late game and gives a buff to his ability damage early game; it also makes sterak's feel like a much better purchase for him as currently his most used ability (q) get's zero benefit from all the ad sterak's provides and renekton isn't really an aa champ. Another thing to consider along this line is that his q deals less than an aa worth of damage (without extra ad from items and runes) at rank 1 while someone like fiora or darius get similar healing capability (and aoe damage in darius's case) while doing about 1.5 aa's worth of damage from their abilities - without sacrificing in the cd department. Read that again and just let it sink in. Literally his current kit pulls him in 2 directions - bonus ad and being very squishy to scale ability damage and be a relevant threat to enemies (base damages and cleaver alone don't cut it), and being tanky (lower base stat scaling, being an hp tank instead of a resistances tank, and lacking spammable cc make him less effective at this compared to others). So he's damned if he does and damned if he doesn't.

Move the armor pen to renekton w instead of his e - this makes it less awkward to apply it and allows you to still get longer stun duration AND armor pen on enemy.

Add armor and mr to renekton ult - again, this gives him a WINDOW of power which enemies can play around. Something like 20/40/60 armor and 15/30/45 mr would seem reasonable and turn him into a better teamfighting tank/bruiser like he's "intended to be" mid/late game. It would also improve his ability to duel in lane but not to an oppressive extent.

Shorter cd on his w and especially his e by max rank. Look at the cd on riven's abilities (another caster-based ad toplaner) and then look at renekton's. Hmmm. And yes I know riven is supposed to be a more spammy fighter compared to renekton, but when combined with riven's primary ability scaling off total ad vs renekton's off BONUS ad, it just doubly punishes the latter. Similarly, riven gets defensive stats from damage; renekton does not - forcing him to build less ad items to scale up his damage or be too squishy. Not saying these 2 should be fulfilling the same role (riven should be squishier but with more damage), but take inspiration from riven's kit and how spammable her abilities are and consider making renekton's mobility more on par with riven's e instead of feeling like a sion ult.
