Questions on Rageblade...? Changes or No?

I've fought a a decent amount of Kogs/Jaxs (mostly jax) that rush it (jax + devourer) in the past since the update. 90% of the time kog appears to become a random threat to the team with a decent amount of farm. Kog isnt as muchof a problem seeing as blowing him up is a simple task, but jax on the otherhand... to put it simply fuck soloing post devourer/rageblade mid gameish. I did just have a game against the two (managed to "win lane" fucking around as support jarvan (idk how) for the first 15 minutes before rageblade, left cait to back she tried to solo kog with a cs lead and 3 kills and about 1 assist worth of gold (she got raped) and i noticed he had rushed rageblade which i thought was something that only ap kogmaw players would build on him but anyways. Apparently the new rageblade is 237% gold effecient even without the passive aoe, and apparently grants one of the highest attack speed boosts in the game (terrifying on jax and kog.)
> Anyways is this something im just going to have to get used to like the sated devourer (personally i hate the item) or are there some plans for it? If I am going to have to get used to it what should i do against people who build it? I've made note to myself to (obviously) cc the living shit out of kog, and not to solo jax unless im a gnar with a qss, a phage, and a frozen mallet ya gotta do what ya gotta do to kite the bastard sometimes lol.) But anyways any tips for countering Rageblade? Or has Riot already announced plans for it ? Like number adjustments or changes or whatever.
