Riot doesn't like tanks atm. They haven't liked em for a while. They said explicitly that they want to have a flashy meta at some point (i think it was a couple months before worlds or maybe at the regional finals)
That said, I do subscribe to the idea of MOVING THE CDR AROUND THE TANK ITEMS
What I mean is, there are quite a few items with 10% cdr and none with 20% or 0%.
Maybe make visage 20% and reduce the MR and for adaptive increase the MR and remove the CDR or maybe even remove CDR from visage AND adaptive and give 20% to abyssal.
"But aren't we at point 0 again?"
No because you rush what you situationally need. Either the 20% CDR along with mr hp and mana (obv reduced stats if its 20% or increase cost)
Or if one needs to stack MR as fast as they can and don't really crave CDR you buy the item with 0% cdr but with more resistances/hp
At the moment, tank build paths are gawdawful compared to apc/bruiser/assassin maybe even ADCs.
compare the components of tank recipes to classes who had their itemization recently changed.
for example are really nice even without upgrading and give either laning power or 1,5 item powerspikes
Oh I didn't even mention true damage creep. Oh, well...
