User blog comment:RoznosicielCiast/One day without Ignite and Flash?/@comment-6906412-20130604075744

Ghost/Smite Hecarim or Nasus jungle all day.

Don't forget Teleport/Ghost or Exhaust/Ghost Vlad or Singed.

Cleanse/Ghost or Barrier/Ghost ADC's, most notably Vayne.

Barrier/Exhaust close-range AD or AP carries, ex. Vayne, Kennen, Quinn, Ahri

Cleanse/Ghost or Exhaust/Ghost chasers, ex. Ahri, Rengar, Kha'Zix, Darius, Elise, Rumble

I feel that Flash and Ignite are not the best summoner spells on a variety of characters and/or matchups, and that the above summoner spell combos are actually legit.
