As of now it’s not something we can report (I.E., not an actual condition in any of the report option descriptions, and it’s not in Gameplay Sabotage). What I’m referring to here is the enemy team pushing up to the literal spawn, forcing the opposing team to stay inside and do nothing, because there’s very little that can actually be done about it (except dying if you go out of spawn).
The only two things that can ‘break’ continuous spawn killing is to build Ults very slowly (come out of spawn, shooting a bit, getting back in; rinse and repeat) and coordinate the use of most, if not all the Ults at once to “clear a path” and push the enemy team back. Or, simply ask the other team in general chat to stop it. Obviously, you’re guessing that merely asking them to stop it has the exact opposite effect and even fuels more “rage” on their part (somehow, even though they are just destroying the enemy team by having their face rolling onto the spawn shield).
So, realistically, the only thing to do is to leave the match since it would otherwise be a waste of time to stay. The ‘practical’ thing to do would be to ignore every enemy player who participated in spawn killing. But unfortunately we cannot ignore more than 3 players at once (and even more unfortunately it only lasts for 7 days). By ‘ignore’ I mean Avoid as Teammate (I wouldn’t want to play with people like that, be it enemy team or my own team).
The game has no actual system in place to prevent spawn killing (I.E. no safe zone outside of spawn, etc) and other than ignoring 3 players max (which is nothing) we cannot report them since obviously there’s no way to “prove” it since whoever at Blizzard is looking into reports wouldn’t know how to even verify if it really did happen and who did it outside of maybe watching the whole replay of the match if that’s something they even can do. And even if they could, they probably don’t have the manpower (or even the will) to do just that on a per-report basis (it would just take ages).
So the big question I guess is this: Will something, anything ever be done about spawn killing?
I’m not sure when this started. I took a break from the game for a long time (more than a full year between mid 2017 to late 2018, and only made a regular ‘come back’ starting in mid 2019). But I genuinely do not recall this whole “Let’s keep pushing the enemy team back to their spawn, stay there and let’s kill them as they come out of it” trend in Overwatch. That’s something I haven’t experienced since probably the early years of TF2 and all the way back to Battlefield games. I absolutely don’t remember 2016 to 2017 OW being like that.
Either something happened that I’m not aware of that encourages it, or a new wave of ‘other games’ players came to OW in recent years and applied their trendy spawn killing tactics into OW and it’s now a standard. That’s the only way I can explain why it’s happening (outside of the OW Team apparently just letting it happen to begin with). It’s frustrating.
