Dark oak wood type

Wood types like Dark oak, pale oak, and maybe spruce, should take slightly longer to mine compared other wood types, this could give people an incentive to build with a more sturdy materials. and these wood types can be mined faster using higher tier axes like diamond giving them a use specifically when people want those wood types, but there wouldn't be an attainability tier requirement because they can always be mine with your fists just slower. potentially if termites were added they would take longer to get infested. or it could be a challenge mod.
