There are 2 issues when looking at Renekton with Conq facing tanks like Ornn
- Compatibility of Conq + Rene is weaker than the compatibility of other champs with other runes.
Conq isn't really a keystone Renekton wants. It's just the best thing he gets when facing tanks.
Afterschock/Grasp is EXACTLY what Ornn wants.
Renekton likes to do short trades in the laning phase and Conq excels at longer fights.
So from the core concept seen, they aren't really compatible to start with.
This was also an issue with FoB but the difference being, FoB also helped in shorter trades, if Conq doesn't proc then it's like having no keystone at all.
Another thing is that the old rune system didn't hold the same power level as the new one (power creep).
Which leads to the problem that certain champions become absurdly strong because they can abuse a keystone better than others can (since they can use the power creep better than others).
Plus Riot thought giving everyone Armor seals as base stats was a good idea ;)
Wanna know what type of damage tanks like to deal?
(Referring to the statement of "only power creeping main stats of champs leads to problems" I told you at the rune discussion)
- 4 second to proc Conq is too long for teamfighting but it's a pretty damn good splitpushing keystone.
Assuming you can't reliably hit minions to have Conq ready, the 4 seconds is too much charge up time in a teamfight since you will be half life by the time it procs (problem of damage creep) so you already have to plan an escape and can't really fight with the active keystone anymore.
On the other hand, tanks have it a lot harder to stop a Conq user from splitpushing.
And lastly, Renekton hasn't recieved the power to bring the champ to todays sandard, he propably needs some sort of % max HP damage or true damage or even more bullshit, % max HP true damage!
Wohooo power creep bois, I don't see a problem at all!!!!!
