Rogues using cunning action to hide after attacking
I have a player who's playing a rogue. His typical turn goes like this:
Round 1:
1. Action - shoots arrow at target and rolls normal damage dice
2. Move - moves out of visual range of the target
3. Bonus Action - Cunning action to Hide. His stealth roll 99.9% of the time is higher than the passive perception of the target.
Round 2:
1. Action - shoots arrow at target at advantage since hidden from previous round. On a hit, rolls normal and sneak attack damage dice.
2. Move - if necessary
3. Bonus Action - Cunning action to Hide. His stealth roll 99.9% of the time is higher than the passive perception of the target.
I get that the player wants to take advantage of the sneak attack damage dice as much as possible, but is it being abused given the scenario described above? Should I allow him to continue to hide after firing from the same relative position round after round?
