"Woah dude, relax. No one is attacking you personally like you are doing right now. True damage is nice, but no where did I say it was inferior, just that it doesn't interact with Runes, Masteries, Items or other skills. And that for twitch, it doesn't scale with anything at all, unlike  Vayne's  Silver Bolts or  Corki's  Hextech Shrapnel Shells. "

1 - runes and masteries and items dont interact with vaynes silver bolts either.

2 - corki has a scaling because it has no base true damage, being based on his total AD, whereas twitch gets a bas true damage per second. also corkis require autoattacks, where as twitches R and W and AA will apply the passive. and i just dnt think AP twitch is nessecary.

"On top of that saying True Damage is superior is not 100% true. When playing  Corki and  Taric in 1 lane you can actually reduce armor below 0, making the true damage that corki has on his AA's be less then the actual auto attacks value. "

3 - While this is true, the enemy would have to have really low armor for this happen. and the true damage will almost always be lower since its only 10% of his total AD
