You are right, it's in the game so it is a feature. I think however that there is a difference between f.e. a long rest, Monks, spells and a mere potion. I did not understand Larian's design of this potion stuff from the first time I read about in in EA. I'm not against effective or even op stuff. But such a potion seems to nullify the whole attribute system for me. I never used it and never will while I'm not against for example using the Globe of Invulnerabilty, quite an op spell indeed, but at least a lvl 6 spell, or the Alert feat, which are not able to break the whole DnD system (only make a huge dent perhaps).
