I would like to see in Epic shop option to buy 12h premium. The idea is simple - I'm not able to sit by PC 24h and therefore a lot of time from the 1-day premium is wasted. So from my point of view 12h premium is more flexible.
For those who think I want more premium time for SC the idea is to have common cooldown period for 12h (3,5 days) and 1-day (7 days) premiums. The result would be that if someone buys 12h premium then next one (12h or 1-day) can be bought after 3,5 days. Buying the 1-day premium disables both items for 7 days.
