Get Rid of that Coin Toss
At the moment, match ties are decided by a random coin toss that determines whether your team will be the attackers or the defenders. The attackers will have to try to capture a point, and the defenders have to defend it. If the attackers manage to capture the point within the time limit, they win. If not, the defenders win.
The problem with this tiebreaker is that the time limit is extremely short, and even in normal control matches, it usually takes a lot longer before an attacking team can rally together and take over a point. The short time limit works in favor of the defending side, and the randomness of the coin toss has left many players feeling a little salty. Besides, ordinary control matches usually give attackers a chance by having two control points they can take over. With only one control point on the line, the tiebreaker greatly favors the defending side at the moment.
Thankfully, it looks like Blizzard will be doing away with the coin toss starting next season. But for now, players will just have to make do with the random nature of the tiebreaker.
