As for Surge - we definitely missed the mark. Originally Surge was envisioned as a team oriented spell, something similar to old Rally. After a few iterations it had to be toned down, but we didn't want to make the user feel worse for taking it. As it stands now, it does come down to which spell is going to give you more damage - Ignite or Surge. In an overwhelming majority of cases, Ignite will actually give you more mileage even if Surge sounds better. This becomes especially true later in the game as Ignite ignores armor / magic resist. Surge was fun to cast, and had good synergy with a particular couple champions - but a majority of the time it was actually a trap. There were some fun aspects of it - turret pushing, clever edge case uses, and getting bigger, but it overall was a false choice.
