OK, fair enough. I definitely consider it tedious (especially when combined with the standard "small steps to get behind the enemy without triggering their AoO" stuff) and didn't realize there are actual mechanics/balance implications because of that.
It also prevents you from getting sneak attack using your reaction. Rogues can get 2 sneak attacks in a round, as you can get 1 on your turn and 1 on other's. If you make an attack of opportunity or attack due to a battlemaster's commander's strike, for example, as long as the requirements for sneak attack are met, a hit on that attack rolls sneak attack damage.
With solid planning and teamwork, a rogue can achieve 2 sneak attacks fairly often in the right party, and sneak attack was originally balanced around that.
Not trying to hound on you here, just pointing out the full potential of sneak attack.
