If there is not enough interest then setting up an OTG guild will be worthless and hurt you in the end, as I know from first hand experience, a’la our mostly empty and inactive OTG guild in Marvel Battle Lines, other than myself. The problem is, even if we create one and there is not a lot of interest within OTG then to recruit outside members we need to get them to apply to OTG, hard to do over most mobile games.
