I see people lost 1v1 in LTS when I'm dead and it's mostly positioning and ammo conservation. Make sure you don't need to reload when you meet another Titan and use your ordinance ASAP, if you are Stryder try dashing diagonally towards them to avoid a reflect and simultaneously punch them or smoke. You want to try your best to attack their sides which is easy as a Stryder, don't run away if it isn't dashing into a corridor or something, never look away as they provokes them to rush you down. Lastly, if you do damage to their main health, that's good. Don't try to kill them completely all the time, in 1v1 as Stryder that will only happen if your opponent makes a big mistake. You can meet up with him again later. Finally, avoid 1v1 lol. As Stryder they shouldn't be able to stop you from running.
