Event with RB was an experiment, it turned out not too very successful. We abandoned the idea of making Invasions with the raid bosses for now. Waves of monsters are carried out not only for 80+ characters, but also for the 75+. Unfortunately there are not enough players under 70 so that they can deal with the waves of monsters, but we will try to carry out this event for them. I would like experienced players to join to these events to help weaker players – invite them to the groups, give buffs from a high-level support.
Also, we are planning to make a nice event with no difference to the level of a character, where everyone will be able to receive useful prizes.
If you have any ideas what game events could attract players - we are happy to listen to them and try to implement.
