Conqueror - What will it mean?

As a toplane bruiser main and inventor of several builds and picks which eventually became meta in high elo - "originating" in Korean solo queue, I would like to give a quick highlight of what I feel conqueror will bring to the table. I would like to add that - while I arrived at this view independent of others' input - several high elo streamers have posted vids after my conclusion which agree with what I believe about this new keystone.

Conqueror - gain some ad and - key thing here - true damage after 4 sec in combat. Melee can refresh this while ranged cannot - so no adc or mini-gnar or jayce abusing this. That is a good thing. However, this rune will in fact empower melee champs I would refer to as fighters more than bruisers. Champs with big bursty spells as their primary source of damage and who want short burst trades will not benefit from this nearly as much as you might think. Also, they will be overtaken by the more aa-based/right click champs sooner unless they snowball early since their resistances and hp will mean less in fights vs enemies who can quickly rack up damage via aa's and which are now ignoring a good chunk of the bruiser's armor.

So, burst trade champs have a window in which they will now potentially be able to burst even harder and just 1-shot enemies; however, if they fail to abuse this window and snowball, aa-based champs will overtake them pre-lvl 10 or so as opposed to closer to lvl 11+. The exact level will depend on rank/elo and skill of each player of course. So champs like renekton and riven - who want short trades - will only benefit from this keystone if... they can sit there continuing a fight while their spells are on cd and live long enough to get off a 2nd rotation to net a kill. If they don't live long enough to do this, they simply lose out and one burst trade isn't enough to make it worthwhile.

Champs that are caster-based but also want more extended trades - like darius - will benefit slightly more.

But the real winners will be aa-based champs and champs with high base attack speed who also build one or more attack speed items and who look for extended trades. Jax, yi, xin, yasuo, shyvana, trynd, aatrox, and irelia (since she's similar to jax, but won't probably benefit as much).

Overall, I don't think conqueror will deliver on it's promise the way people hope. The darius and renekton and riven's of the world will not benefit from it all that much unless they snowball between levels 1-7 and build up a massive lead. Otherwise by level 9 or sooner, a jungle yi or xin or a toplane yasuo or jax will 100% just abuse it better than them and be able to delete them with eventually no hope for the bruiser. It will be completely broken on some champs in it's current state - the % of true damage is far too high to be healthy since the 4 sec in combat part can involve just hitting minions currently. Thus, a bruiser or fighter can - if allowed to stack up via killing minions - potentially flash 1-shot an adc thanks to the true damage where currently the adc would survive on low hp. It will empower tower dives by squishy champs vs tankier toplaners (bruisers or tanks) far too much mid/late game.

Perhaps the better route would be to make it give % armor pen and some bonus ad instead of true damage. This would help it achieve it's primary purpose of helping bruisers kill tanks better without making it quite so punishing for opponents of all types from mages to tanks to adc's to bruisers. Alternately, the rune could be reworked altogether into something different. If it stays as-is, I predict many posts about the absurd damage champs are doing, total changeup in power spikes for toplaners and junglers, and an eventual nerf until the keystone either gets reworked or nerfed to the point it is potentially too weak. Regardless of what actually happens though - expect people to eventually catch on and see a lot more xin, yas, yi, aatrox, and jax especially. With of course the darius thrown in - especially at low elo - for his early game snowball potential thanks in large part to his bleed keeping it active even if trades are not constant.
