Not at all. Those are standard in game events just like any other game.
Doom is talking about adding a separate thing from standardized "holiday" events where you can. "earn a separate type of experience to level them up" TBH 99% of games are doing it now. SWTOR, New World, have their own take on an MMO stylized battle pass. Which is really interesting. Keeps players engaged for a few months without the developer having to rush to implement new content every couple of weeks to keep their community engaged. It also reduces the necessity of adding additional stress to staff to run in game events. So they can focus on implementing QoL updates, new items, and content in the future. SWTOR, and New World utilize their battle passes as a Time Stamp for when "roughly" the next season/ Content patch will release.
I like this idea. and I second it.
