The other issue with blur was the fact that if you had a somewhat bad computer back in the day, you would turn off shadows to increase performance a bit.
Meaning the hero whose model would become 100% invisible, and would be represented only by a shadow, would become extremely hard to target.
Yeah.
PA was fun in those days, since when she first came out she pretty much had 3 passives and a Blink Strike, making her either the weakest or the strongest character on your team, depending on her farm. Now, though, she just gets an innate 4x crit and 35% dodge, she can hit insanely hard with a damage item or two, and having a gap closer and slow allows her to pretty much go for lifesteal/bash/damage/attack speed, without needing a Butterfly. The "nuke" ability allows her to farm with some ease, as at level 4 of the skill it's a 200 true damage (on creeps) nuke for 15 mana, meaning she can sit in lane and farm all day at range, and the pseudo blink allows her to target friendly units as well as enemies, enabling her to move in and out of battle every five seconds.
Great carry, but easy to shut down early, and a monster if she gets even a mediocre farm. Just get a Battlefury early on and you're golden.
