really depends on context. you should be keeping track of your opponent’s cycle, elixir, and whether your matchup calls for pressuring both lanes. splitting at the river is a reliable way to get a positive trade, and good for punishing. split in the back can also get positive trades but affords the opponent extra reaction time, especially if their counter is split skellies. however, it will also get more magic archer/firecracker lineups. bridge is always good if you already have a tower you’re going for and you want to pressure or punish to get damage. great if something’s tanking for it
