I mean, i am pretty much sure they are the first ones to be upset about it, way more than we are ourselves.
Think about it, most the world has been on lockdown for 2 months, that was literally the perfect, most ideal scenario for a MMORPG to release, with literally milions of people bored at home and available to play.
I am sure they did all they could to release on time once the threat of lockdowns loomed, but i guess it was too little too late by then.
Sure, we are upset for what happened, but i am sure they are ten times more upset than we are, missing that chance & the profits.
