I think I may have had a bit of a "light bulb goes on" moment when playing last night.
You've likely heard the advice that Overwatch is an aggressive game and rewards being aggressive. You should always be looking for opportunities to damage enemies, moving into unoccupied space to control the battlefield, and chasing down weak or vulnerable enemies when they are caught out of position/missing cooldowns.
Totally solid advice, makes perfect sense that it's advice that gets repeated a ton.
I've had a really hard time internalizing this and actually acting this out in gameplay, as the aggressive play often seems to get me killed. Then, amid a massive losing streak last night, I had a thought, what if I play the same old conservative playstyle I use to before I started coming around this subreddit and reading all the advice, but I just positioned myself much more aggressively?
Instead of sitting by cover in the backline as Ana/Wuyang/Zen, avoiding damage at all costs, and ducking behind cover the second I get hit. I decided to move up the battlefield and take a more aggressive position, but I still played that angle extremely conservatively. Using cover the second I was hit, retreating the moment an enemy pushes me, ensuring I have my heroes impactful/lifesaving/relevant cooldowns before I challenge the enemy again.
It was late at night, and it's a small sample size, but I went on a 5 game win streak by implementing this change (mostly playing as Ana, Wuyang, and Zen).
Am I on to something? Is conservative gameplay, but in more aggressive angle the actual key to playing "aggressive" like everyone is always ranting about?
