Currently just some classes have plenty of iframes, namely sorc/kuno/ninja. These are game-breaking when they can be done in as plenty as those classes can. Solution would be limiting the iframe by having some global cooldown 10 or 15 sec per iframe and otherwise the skill that would do iframe just gives an SA to the player. Another solution could be with the rework of BSR. Let BSR dmg and cc potential to go through iframe with say 50% efficiency, in essence removing iframe concept and making it more like a SA+ than "iframe". And I am sure a lot more solutions are there but first thing is to acknowledge that iframe in current PvP meta they have made is from earlier meta where it fit but in current PvP meta it is way way over powered. So please other players give more suggestions and solutions how to fix this and Kakao employees please forward this to the dev-monkeys at Pearl Abyss, thank you!
