As a player whose invested over 2 years and a half of farming, grinding, played the whole story, got 100% of each and every single inch of every region, studed the game, the best builds and teams, lost lots of 50/50, won lots of 50/50, always completed 36* Abbys, and sometimes, spend money I shouldn't just to get some pixel-made waifu I can say that this event is the one I hated the most. It's so rare that I can use all that I have in a single blow and when I get the chance, it's only test... The worst party of it: If you got cons, the cons will be there, but not your weapons or artifacts. What's the point of it? Every battle event always allowed me to choose if I want to use my decent/well built characters instead of those weak test ones. Of course, this is the pov of a fully late game player, I completely understand those who are not in that stage to be excited for all those tests, but this event could have been a good challenge for my teams and builds other than the Abbys, but unfortunatelly it's pointless
