So obvious every single player in those groups (who btw are just the same players on different runs add or minus one player or two) is meph buffed xd. That's like a whole day a run considering that 1m points is just around wave 70.... One of the leading reasons why meph needs to be nerfed badly since these scores are just outrageous and impossible to achieve without that pet. I'd say the best you could get without meph would be around wave 90-100 maybe a little bit more if everyone plays good but meph just boosts these guys to wave 500+
