Implementing both F2P/Sub is also an option

oK, If the game became part F2P or full F2P, then it could come to numerous things, like even longer time periods between patches or lack of content.

This right here. Patches would definitely not happen every 3 months anymore, it's impossible to budget on a F2P and make
any kind of road map. You don't know if you are going to have to fire staff or cut back on resources month-to-month.

Wouldn't be a fun time if that had to happen, you're looking at possible 6-8 months for 1 patch if not enough people play.
