How come Barrier doesn't last as long as Ignite?
I learned this yesterday after dying to a Kat ignite while trying to protect myself from it with Barrier. It ended before ignite did and I died.
So why does Barrier have a shorter duration than ignite? I get that defensive options don't really fully counter offensive options in league, but I figured Barrier was a good counter to ignite and a great spell for midlane champions that want a bit more survivability.
