I can fully understand the current 6 days decay, specially in the early time of the game.
However is there any long term plan to raise this? And if so, for how much. Personally I would like to see 15 days decay max.
In ARK they use decay timer based on building tier as well. Maybe it could be possible in Conan Exiles too. Say T1 6 days, T2 9 days and T3 15 days.
In the long run of the game it would be beneficial to cover 2 weeks in terms of decay for normal life events
