Garen QoL improvements please

Hello.

I would like to have a few QoL changes to Garen, namely:

1. His E: Judgement to end as soon as the damage ends (right now Garen spins for 3 seconds, while the damage is only dealt for 2,5 seconds - basically adds a half second at the end where Garen just spins for no reason). The last 0,5 seconds should be removed.
2. Again, his E: Judgement allows him to ignore unit collision, although it does come with a slowing effect (20%) when spinning through minions. This slow is in effect even if Garen have other sources of ignoring unit collision (such as Phantom Dancer or summoner spell Ghost), even though the other effects don't have a slow penalty. His slow penalty should be removed if he ignores unit collision from another source.
3. His W: Courage passive should list how much Armor and Magic Resist he gained through the passive.
4. The ingame tool-tip for his R: Demacian Justice should show the damage dealt as percentage of enemy's health missing. So, instead of this: "dealing 175 magic damage plus 1 damage for every 3,5 Health the target is missing", it should just say this: "dealing 175 magic damage plus 28,57% of enemies missing health" (or you could even make it into 30/35/40% of target missing health instead of 28,57/33,33/40% - a very small buff to Garen's early, but it would look much better).
