Now that you know a bit more about hero roles and what each hero can do, it’s important to understand how that role plays into your positioning on both a macro and micro scale. On the macro scale, your role determines where you need to be on the map at any given time. On the micro scale, it’s all about positioning in teamfights and skirmishes.
Macro positioning is difficult to explain fully without an extensive guide on lane configurations, but I will do my best to lay out some of the basic ideas. On all maps, side lanes generally belong to solo laners while the other four members inhabit the other lane or lanes. Side lanes are generally “safer” from ganks compared to the mid lane but are also more isolated, especially on large maps where objectives can spawn far away. A few players tend to roam between lanes looking for ganks.
First and foremost, supports should almost always be with at least one other teammate to maximize their healing value—some exceptions can be made for double healer compositions or Rehgar, who also happens to be an excellent jungler. If you are sitting in a lane alone as a Lúcio or some other low impact support, you’re often in the wrong place. It would be more beneficial to join the rest of the team than to soak the lane, even at the cost of experience. This is a very common mistake, especially at low level play. Do not solo lane as your team’s solo support; always be next to the majority of your team.
Heroes with globals like Falstad, Dehaka, and Brightwing get considerably more value from side lanes. While soaking in a side lane they can still quickly travel to the other side of the map and help out with objectives or teamfights. In addition, side lanes build up more minions and push harder due to the extended length of the lane.
Tanks will generally lead rotations and look for ganks on other lanes, but that is not always ideal, especially in weird Quick Match compositions. The main thing you’re looking for in rotations is good CC and damage from heroes like ETC, Tyrande, or stealth heroes. In comparison, Lúcio, Zarya, or Nazeebo are usually not ideal for rotations due to their low burst, poor waveclear, and lack of CC.
Sieging heroes tend to have weaker rotations but excel at pushing an individual lane with their good sustain and/or long-range damage. On two-lane maps without big rotations like Braxis Holdout or Haunted Mines, these heroes gain substantially more value. Ideally, you want three or four heroes in a sieging lane (usually support, siege, and one or two DPS), but this may not always be possible in uncoordinated games.
Don’t forget to respond to your opponent’s composition either. For instance, if you’re playing Alarak into Chen, you know you always want to follow the Chen around so that you can prevent him from pushing. Heroes of the Storm is more dynamic than just choosing a lane and playing against whoever is there; you have to actively change tactics depending on the situation.
When it comes to fighting, your positioning is largely determined by role—the tankier you are, the more aggressive your posturing usually is. By extension, tanks should theoretically stand in front with assassins slightly behind them or to the side, and the healer should be standing safely in the back. This setup is never static and constantly changes, but it’s an important concept to keep in mind.
As a healer, your number one goal is to stay out of harm’s way and keep your team alive. When you play too aggressively as a support player, not only are you wasting your healing output on yourself, you are also putting yourself at risk and forcing your team to spend precious resources trying to save you rather than focusing on the proper targets. Certain supports like Kharazim and Rehgar lend themselves to a more aggressive playstyle, but a certain balance must be struck between passive and aggressive posturing.
Tanks have to maintain a distance between the back line and the enemy team. One of the biggest mistakes for newer players is to jump headfirst into a fight as a tank because it’s easy to stay alive. However, when they opt for this YOLO playstyle, they tend to neglect their primary duty as a tank, which is to shield the back line from danger.
Likewise, assassins should avoid a gungho approach. As a rule, the tank should be in front of the rest of the team (with a few notable exceptions), so if you’re an assassin, especially a ranged one, standing in front of the tank during a teamfight is probably a mistake. Ranged assassins should follow the tank during fights and allow them to soak as much damage for them as possible before making any very aggressive plays.
There are some assassins, particularly melee assassins, that excel in getting good flanks and deleting someone in the back line. I won’t go over this too much, but it’s important to constantly weigh the risk vs reward of the situation. Often, the safe play is better than an overly ambitious engagement.
