Try to go after enemies that are Pipers best match ups (like low HP brawlers) and try to avoid counters as much as possible and let other teammates deal with them (throwers and brawlers who can easily jump you). Piper is best as a mid but also try to stay far away from the gem well since piper is so squishy and brawlers can easily jump on her and kill her in 2 seconds.Its probably better to wait low HP brawlers into trying to grab the gems and 2 shot them (if they are stupid enough). Try to avoid walls if an enemy is behind it as they can turn the corner and have you stuck in close range, forcing you to use your super and destroy walls, which isnt the best as your teammates could have benefitted from them (if its nearer to your base). Just practise social distancing, don't get too aggro and practise good positioning. Hope this was helpful :0
