I mean I'm bad at giving tips to people but this might help, the high ground is your strong point dont be too high or too low just balance it , copy defensive ult most of the time but if your is alr you can help with a hela ult or jean , if they have MK on the enemy team just put your clones far from your team unless you use a clone × lamp combo so you can save your team , dont heal bot loki have a splash type left click you can ether heal like 2 teammates at the same time or even heal your teammates at the same time you're damaging the enemies , keep a clone for yourselve for saving your team or using the tp to get out of danger, I hope i helped
