Ideas for Katarina in the assassin update.
Katarina definetly needs some looking, since some of her kit is insanely weak then some of it is insanely strong. (W, E being weak - Q, R being strong). My proposal to balance it out:
Q base damage increased by 10, but increase per level decreased by 5. AP ratio for first tick decreased by 5%. Will give her a better early-game but a less overpowered Lategame.
W movement buff increased to 2.5 seconds instead of 1. Movement buff % increase by 5% per level. AP and AD ratio increased by 10/15%. The movement buff is pretty unnoticeable right now, and the ratio is pretty low for a bursty ability at the moment.
E- Noticable changes
AP ratio increased by 5%, base damage increased by 20/30/40/50/60. Instead of removing damage taken after teleport, increase damage dealt. Damage increase: 10/12/14/16/18% for 1.5 seconds. Teleport range increased by 75.
R- Major changes
Range increased by 150. AP ratio decreased from 2.5 to 1.7. Duration decreased from 2.5 seconds to 2 seconds.
Minor change: Cause the first blade an enemy is hit by to deal 4x the damage of a normal blade, cause subsequent blades to deal 65% damage.
This will increase her basic kits power while decreasing the unesscesary power on her ultimate. However, the change to her ult will give her more power as a burst assassin instead of making it rely more on dealing damage over time. It also gets a longer range so enemies can't stand out of it so easily and kill her during it.
