Why even bother complaining about Casseiopeia's changes?

When about 90% of League players be busy using other suitable mid assassin champs like pentakills Katarina, team carry Zed, burst assassin Akali, ez escape Kassadin, nuke bomb Syndra, chomp chomp Fizz etc. Why would you be wasting time coming up with good/bad points as if you main Cass right from the start of changes when in reality, you don't even know Cass existed? Yeesh.
