To meddler on olaf
E) increase the cooldown at early levels and increase the cost back to 40 percent of the damage value. In exchange olaf's E now applies all on hit effects, most importantly, minion agro and lifesteal. With this change you will accomplish three things. 1) change the abilities scaling so it is drastically less effective in lane (where honestly its the biggest problem) toward late game 2) create an incentive for damage builds and make them feel satisfying for the olaf player (another area where hes kind of wanting) 3) return a old interaction between w and e as well as adding counterplay and stressing the importance of w as a long cd meaningful trading tool throughout the game (clarity) as well as solidifying and placing more importance on his sustain tank thematic
From my perspective his q is bogged down by two different design goals. -olafs q power should come from its poke and ranged damage as well as vision -olafs q power should come from its slow and ability to catch opponents
You should probably explore one of these and not both at the same time!!!
As a designer you went out of your way to demonstrate that q would be alot less of a poke tool. Even though removing ad from W was more targeting this position in the rework, you decided to take ten damage off of q at all levels. your goal here seems to be absolutely clear that his q doesn't have its power loaded into poke.
While this may be fine the nerf to olafs q slow seems to be targeted at what the community and the pro scene sees as problematic inside of his kit. When olaf can catch people he is an overwhelming champion......So the balance team nerfed his slow leaving an immensely unsatisfying olaf to play
Because of the above results of his changes i think you have two options to change olaf either increase his q as a ranged wave clear and poke tool (increase ad ratio base damage ect and remove some of the slow) or stick to your original guns and shave the fat off this multi purpose tool so olaf can catch people when he needs to (increase the cd when he doesnt pick up. lower base damage ect)
Heres two very quick and easy to test changes that arent ridiculously playpattern altering....
You touched upon the fact that olaf's passive combined with his w giving stacking attack speed feels unsatisfying. There are an infinite amount of ways to modify a stat passive and im sure you can come up with something unique
