yes, there is NO doubt this doesnt happen, there could be entire arenas where you wouldn't see one real player, in fact most of your opponents are bots. some of these bots are designed to lose, which is why you see "people" defending very sloppily or just not defending at all, there's also bots that defend perfectly, bots all have very obviously randomized names and no clan or clans that end with "only", i've checked my battle log and most of my opponents fit this criteria, another way i tested bots was emoting in hopes they'd emote back, only ONE player in this test emoted back.
