Playing on a team-based online game is quite challenging since your actions might either lift your team up or drag them down. On that notion, you must be flexible enough to know at least 2-3 roles in order to have some options under certain circumstances. In most games, it is a hassle to see some teammates forced to play the role that they are not comfortable with in order to fill the missing role. Though Overwatch applies a system that enable players to change hero in mid-game, however, concerns like those mentioned above are inevitable.
According to the report from Gamespot, each of the heroes of Overwatch have their own unique abilities. While others are easy to play, it is still important to know how to use them effectively during matches. In addition, it is also important to utilize most of these heroes especially playing on competitive.
Based on the report, it is expected that Overwatch will add more characters in the future to apply variation on the game. Most Overwatch players are spamming the new character Sombra in order to explore this new offensive hero. Sombra is known for her hacking skills which allows her to hack in-game health packs and opponent's skills for a limited span of time.
She also had a Translocator which enables her to freely enter and exit the frontline easily. Lastly, Sombra is also known for her stealth ability to sneak around the opposing team and attack them at an opportune moment.
Another fan favorite hero of Overwatch is Mercy. This support character is adept of using her healing and ability buffs to maximize the potential of both tank and offensive heroes. In addition, Mercy can revive fallen teammates using her ultimate and quickly enables them to be ready for battle.
These are just highlights compared to the long-list of Overwatch heroes currently present in the game's roster. Check this link below to know more about how to effectively use the other characters such as Lucio, Genji, McRee and more.
