Due to the AI (Summon waits for target tower to be destroyed before attacking other towers), Summoned warrior will have some delays, especially if the tower can be destroyed with one breath.
How about speeding up the Breath projectile speed to 300? (as fast as Nollaig’s Winter’s Breath and UVS’s breath). Therefore the delay can be shortened even more.
Bonus for adding low priority for destructibles (especially monuments).
