User blog comment:StrategicMagic/Carry by Proxy - Why (Some) Assasins Don't Fall Off Late/@comment-5556439-20121207155801

In my experience, "Falls off late game" describes how well a champion or item SCALES into late game. If a champion is like Katarina, and has so/so ap ratios, but very favorable output just by leveling your skills, she wont fall off, because how much she gains from leveling plus AP just adds to her output. LeBlanc isnt like that, but has higher AP Scales. Theres a reason why its called "Late Game". I disagree with the whole "it only seems like she does" no, she doesnt really compare with other AP bursts because she just straight up annihilates single targets with low to medium amounts of MR, but overall Brand, Annie, Ori, Lux etc are significantly more viable and are much stronger picks. If you like LeBlanc, then just play Kat, because she has AoE + Burst + Escape + Presence, and she is much more threatening in general.
