In addition to the Solar Crest, a new evasion-granting item, 6.84 also brings changes to how we can deal with evasion and blind. The relevant patch notes are:
Reworked the Item Silencing and Passive Disabling behaviors. Break disables the bonuses of passive Abilities only (in 6.83c Scepter Doom and Hex applied this state) Additional Note: Evasion, Damage Block and Critical Strike no longer have special classifications on how they interact with the above. They are only disabled if they match the general rules of the above.
Hex no longer applies the Break mechanic [?] Affects Scythe of Vyse, Voodoo, etc
The biggest change here seems to be the nerf to Hex ("Hey Lion ( ° ͜ʖ͡°)╭∩╮" - Icefrog). Blinds can still be removed and Break can deal with Drunken Brawler and Blur, but MKB is now the only way to deal with Windrun and evasion from item passives.
