Do ticks have any redeeming qualities?

I can't stand ticks, but I keep hearing that every creature has its role in the ecosystem. Can anyone shed light on what good they actually do, if anything? Just curious!

While they do play some role in the ecosystem, most ecosystems would probably keep chugging along just fine without them. They're not exactly the stars of the show that everything else relies on.
