Aye aye I’m the lucky guy in the video at first we went with strategy without reprog doing rusted and summoner at first then grinding for avenger, but I decided to take reprog and it was worth it (rusted first then sky hunter and with the power of dashers just ez destroy first 2 bosses which are speedster and M-Menace, then engineer should cook)
I think what reprogrammer betrayed is very good for start and early game def, but classic betrayed helps on late game. So they both good, but i guess its better to use reprogrammer and just cook your enemy with lightspeeds.
