I don't see how it's more time consuming. You only have to wire controllers once and then you can change tilling as much as you want, you don't even have to switch between different materials, as controllers are accessible within slate view window, unlike other maps for which you need to open them in parameter editor first. Once you done wiring for the first time, you don't have to do that ever again, because you can copy material, save it to your library as template and controllers will stay intact. Using controllers may look inconvenient and cumbersome at first glance, but when you try it for a few times, you realise how powerful and flexible they really are. C'mon, just give it a try ;]
