Or it might make even more people join. Everyone bots to some extend, no one has time to grind and repeat same process every month from zero to hero. That's why servers die, and why old 8.6 servers were more fun and lasted longer.
As you can see all the servers are almost completely dead, all communities 7.4, 7.6, 8.0 and above joined into one and play the same server that barely have 2 teams. They have to arrange battle over facebook and discord since there are no enough players, so yea, bot might help if not on this server, bot will make a return or OTs will completely die out.
