One tangential issue that's been brought up here could be solved with the following perk:
Trigger Spell
You've learned how to hold a spell for a few moments and release it with a single thought. You can choose to treat the last turn of Concentrate in spell casting as though it were a Wait (with the response of "the spell is cast"). You must either complete the spell before your next turn or it dissipates, either way you pay the full energy cost. You must specialize by spell.
If combined with Continuous Ritual, each Concentrate to keep the ritual going also acts as a Wait. If you take any action other than Concentrate before the spell is cast, it dissipates as above.
