Well, perhaps it can evolve over time just like 4e, and in the meantime, the modification library can substitute. The only thing we need is a mechanism to support these mods. That is, where you can put in a round countdown timer for a fixed time mod or the ability to set the timer as the effect goes on the CT. I think this would tide us over just fine, and we could wait for the more sexy auto-mods (I could personally wait a long, long time for that).
