Now the CβT signup and Prologue 3 news has simmered down a bit, it's probably a good idea to draw attention to the third occurrence of arguably the worst type of campaign PSO2 has to offer, revealed in advance during Prologue 3:
The returning players portion of the campaign usually requires players to have not played PSO2 for some time - generally a month prior - but to have played before that point.
This means if you have anyone in your alliance who hasn't played since the 14 April maintenance, it is in your alliance's best interest for them to not log in until after the 12 May maintenance so they can qualify as a returning player and get everyone an emote Global has never had before and which is likely to be quite expensive.
Honestly this iteration of this terrible campaign type is even worse than it usually is, especially on Global because the only way for a returning player to qualify this is to not log into PSO2 on purpose and miss most of the ARKS Appreciation Event rewards in the process. The only way for an alliance to get 545: Kneel as a reward is for one of its members to sacrifice their ability to get 283: Dance 41, 451: Elaborate Dance, 376: Groovy, 478: Cross Legs (a revival PC players already missed once btw), 477: Rainbow Drop Acquired! and a ton of accessories, weapon camos and rainbow keys (likely harming their ability to complete the level 100 campaign)!
But hey, if you have someone in your alliance who's been away for a while and they've taken a renewed interest thanks to Prologue 3 and the upcoming Road to New Genesis campaigns, see if you can convince them to avoid logging in for another 2½ weeks because there's a reward in it for you.
