Quite easy actually... the team was 4 melee and 1 ranged. Ranged got mid, me and my lane partner got Lux and Graves as opponents.
In short range, Lux Bot rarely misses and Graves' shotgun really kicks. One shot each took half hp, then Graves finished us off easily. Please remember that bots pretty much lock on when they use abilities so dodging is a bit harder when dealing with instant reaction.
Also, being overly aggressive gets you killed easily.
The rest of deaths were a very successful combo of poor planning, bad timing and lack of coordination.
An example of one death was when i charged ahead on our side of the bush with my lanemate coming from behind, got Graves below 50hp then died to Lux. Looking back to search for my compadre, they were afk behind the tower. I was sad.
Another death was after a fight. I was low on health and as soon as i was in range, Graves insta-R'd me. I wish i could act that fast...
Yeah.... It's things like this that make me glad i'm staying very far away from ranked and normal matches. They're demanding more than i can provide...
