A style that exploits their tendencies:

Their biggest weakness is their haste in trying to force a play to happen, leaving their backline exposed and giving away a lot of angles just to get in your face ASAP.

To exploit it, we’ll play a reactive style and put defensive resources where they’re strong (their frontline), while abusing their lack of map control by taking flank angles greedily to get angles on their backline. The bulk of this post are guidelines on this proposed playstyle, but it’s far from the only option against over-aggressive teams. You’ll find smaller adjustements you can make throughout this post, and what to cut down on if the style as a whole is too far out of your team’s comfort zone.

The following style can be used both as a preparation for a specific team and a simple mid-map adjustment if you notice the enemy team is getting hasty under pressure, and starts to rush things too much.

An average city center first fight setup, very strong at its front, trying to gain control of the center.

Here’s what your default positioning should look like. I used city center because it’s a very symmetrical, wide map with a central point that teams typically try to control. When I speak of center in the future, I won’t necessarily mean the literal center of a map, just the centermost area that’s worth controlling.

The kind of setup we’ll use, passive center + aggressive flank control, able to collapse to its Zen from all angles.

Winston playing off-angles, securing control of flanks and avoiding any trade with their tanks until they commit.

Zen staying in a pretty central position, he is the MVP and both sides must be able to collapse onto him if necessary. Mercy pocketing him rather than Pharah. He is both the bait and the player that gets every defensive resource. This map shows a team spread pretty wide, but if your setup looks narrower that means your team will have an easier time protecting zen, meaning he should position even more aggressively. Same concept goes for any backliner if they don’t have a flank to use, just happens most often with Zen.

Dva between the enemy frontline and your Zen, giving up center control, not fighting their tanks or trying to make anything happen with her shift, but close enough to Zen to be able to peel in time.

DPS playing flank angles, not taking any fights they can’t solo as they won’t get many resources. Only there to control flanks greedily, then use them to take over the whole map if uncontested (this can mean widow flank, pharah/flanker dps all-inning their zen, etc).

By giving their tanks nothing to do other than sit on their map control, you exploit their tendency to go in too soon rather than work with their team to gain even more map control. On some very narrow points you may have nothing better to do than trade with their tanks, but the same concept of giving up a little space + using Zen as bait and overprotecting him applies.
