- Always focus slow moving supports (particularly zen and mercy).
- Your aim stats are decent. If you want to get better, I would suggest taking time for each shot at first so you are more accurate and your pace will gradually pick up.
- Know when to switch. If the enemy is running Winston, genji, etc. the best thing you can do for your team is switch.
- Positioning is important. Go for spots on high ground and don’t try to flank. There’s very few situations where a flanking widow works.
- Try to predict where the enemies are coming from. If you see an enemy run behind cover, aim to side of the cover so when the come out you have a shot lined up.
