Olaf Change @Riot

Hey riot if you see this post just had a question about Olaf. You guys just buffed his ult a lil bit which was a nice change. Are there any future plans to change his kit, Like his w I feel as if his kit is too ovreloaded with attack speed. There hasn't been a post or update on olaf in a while. You stated in the patch notes of 5.9 that "giving him the speed boost doesn't solve all his problems" does this mean you know there is something wrong with him and will work on it In future? Any response would be Nice
