Still waiting for AD Casters to be fun

In one situation, they make their opposing laner a 3000HP minion and in the other, they become one. Either way lategame is generally pretty bad unless they get help.

Riven and Jayce are pretty good examples. Both have good AD Scaling and snowball hard, although Riven arguably has a significantly better late presence. In the event that they don't get fed you might as well be fighting a 4v5 for all the impact they have.
