The third benefit of the Mobile feat says (PHB, p. 168):
When you make a melee attack against a creature, you don’t provoke opportunity attacks from that creature for the rest of the turn, whether you hit or not.
If I take the Mobile feat, can I choose to allow an enemy to make an opportunity attack against my character, even if the feat would normally allow me to avoid it?
Regarding the rationale, mechanically my character sometimes tries to draw OAs that might otherwise hit others, and it often reinforces the roleplay of the character's personality. Is it possible to "turn off" this benefit of the feat in order to encourage enemies to use up their reaction?
