https://www.youtube.com/watch?v=pLFRCuvuuCsThroughout recent years, we've seen champions designed to counter others that traditionally have an advantage over them. For example, Destroyer is immune to slow debuffs, some science champions are immune to bleed and cosmic champions often resist nullify or fate seal effects, or can even punish them (Maestro). Now I personally don't mind this, as this helps diverse class relationships, but as seen in this video above, this is a 51 sec Sassy fight against a Photon. This is pretty fast, even with class disadvantage.
So the question stands, Are these relationships still as important today as they once were? Why or why not?
