1.0 Stone Recast: 6 Seconds
ARR Stone Recast: 4 Seconds

1.0 Aero Recast: 6 Seconds
ARR Aero Recast: 4 Seconds

Both spells share the same cooldown timer in ARR, so you can't cast a spell immediately after using one. 1.0 didn't have this, so you could start casting a spell as soon as the other was done, while you waited for the other cooldown. 1.0 had more "spam."
