What, are you fucking r00fling me? You linked to one single game of Renekton being played, which proves nothing. I linked to hard statistics in a high-level tournament.
Did you even check the links I provided? It's 2 recent tournaments, where Renek was picked plenty. As far as I know, no one has taken the time to do pick/ban statistics on the two tournaments, as IEM usually craves a lot more attention, due to the bigger scale. And honestly, I wont take it upon myself to do so, just to prove a simple point, if you aren't even gonna check the links I provide.
Also,
here is a link to pros playing twitch, I guess he is a top tier jungler now hue hue.
I believe it was you who started the "but pro's do/do not play him" argument, and now you're saying it's invalid. You claimed he wasn't played, I linked material that proved you wrong. You base everything on 1 tourney (although the biggest recent one), and evne a tourney on a patch before the nerfbat hit the most commonly played top lane, in an ocean of recent tourneys that you do not appear to have been following - I don't think we're on equal terms in this argument.
In any case, renektons viability remains to be proven
I agree, and if I've come across as trying to prove that he's top tier, OP material, I am at fault.
So far he has has utterly underwhelming appearances in tournaments
I assume by underwhelming appearance, you mean lack of appearance, which is hard to contest.
EDIT: Also, I don't think I've said anything that would lead you to believe that I disagree with armor being cheaper, I just made the comparison to show that it is by no means hard to get MR without gimping yourself.
I'm not sure why this was even brought up though, as this applies to Lee Sin, Riven, Olaf + Irelia (less so bc of true damage) and other AD top bruiser I may have missed as well as Renekton.
EDIT EDIT: CLG.eu vs. Fnatic in FnaticRaidcall tourney finals is on right now, Wickd has picked Renekton:
