it depends what you see as decent, there are definitely rewards but youre not buying a relic with them
these modes alternate every season, are disabled every other hour, and have arbitrary limitations in parts as a sort of “challenge”. these gamemodes are barely permanent, if i wanted to play BFU right now, i would have to wait until next season, and i would have a 50/50 chance its offline at this hour
i never said i dislike good changes. thats my position. i welcome new content unless it ruins the game and/or is p2w, which is exactly what we get every update
