Laneswap
Strategy breakdown
Why would a team do a laneswap?
Well there're 4 main reasons;
1. Your adc and support combo is weaker than the enemy's, and you want your adc to farm safely without trading.
2. Your toplaner has a very bad matchup against the enemy toplaner and you want to help him out early on.
3. Your adc and support can take a tower and push significantly faster than the enemy duo lane.
4. You want to deny the enemy toplaner for some reason.
If your team is in one of this 4 situations, you can execute a laneswap, yet everyone has to stick to the laneswap plan to make it worthy.
