A lot of the abilities are instant use. I am assuming for lasting abilities that buff or change the tower. Etienne Level 15+ UCAV ability (but not Level 20) lasts for 45 seconds or 3/4 uptime. For towers, Grand Saboteur has 3/4 uptime and also last 45 seconds. To my knowledge there are no abilities that last more than 3/4 uptime. Hope it helps!
