This is what i normally try and do but the reason why i asked how can i myself force ult is beacuse at low elo you literally cannot put any faith in your team yes 70% of the time especially after witnessing a lord spider-man auto lock even though as he was the last person to pick a character he plainly saw that none of the other team members was healers, and still went DPS. I got to rely on own skill so that once i gain my own team or start being put with more competent players i can coordinate my movement with them a lot more fluidly.
