Hi there and welcome to the forums,
I have to agree with you on this one. I think the amount of Boss Games per match should stay the same, but the variety of Boss Games should increase. They currently only have 2 boss games, which doesn’t seem like a lot. They could possibly turn the “Stand On Color” Microgame into a boss game, but repeats how many times you have to stand on the specific color, like Block Party (a game mode on other servers).
I can think of a lot of Boss Microgames that could be added, such as "Defeat All Mobs". You could possibly make a thread of some Boss Microgame suggestions. But I definitely think that there should be more of a variety of Boss Games, as I think you can agree, the current ones get quite boring the more you play them.
Thanks for your suggestion, +1 :).
