The answers to this question address when it is appropriate to freeze your lane but in practice I am struggling with the how. When I'm playing adc I find it hard to keep the lane in one place. If I want to push I will constantly auto attack the minions and throw in a few abilities and if I want my lane to be pushed I will only attack a minion to score the last hit. To keep the minion wave in one place I imagine I would have to exert the same amount of pressure on the lane as my lane opponents (a tricky balance to maintain).
So are there are techniques, tricks, or rules of thumb to keep in mind when freezing a lane?
The champions I play most bot lane are Miss Fortune and Ashe so tips specific to those champs would be much appreciated.
