On a side note...during DOS2 EA did people complain about this? (free weapons switching during combat, food...?). Or was it already implemented like now (takes action to use).?
This wasn't really an issue in DOS2 as weapon type was linked to your "class"/specialization. You would specialize or be horribly sub-optimal. Swapping weapons was prohibitively expensive in terms of action points unless you were playing "lone-wolf"/solo who were overcompensated with more action points (to the point of making solo-play easier than playing a full team).
