I'll bring two perspective, standard user/player perspective, and streamer perspective.
I want to discuss that Blizzard should ban/remove all barcode accounts from the SC2 ladder.
edit: CLARIFICATION - when i say "ban" in the title of the thread and in general, i mean "abolish" or "remove" barcode anonymity from the ladder. Not to literally ban everyone with a barcode account to be unable to play. Just clarifying.
Ladder play is supposed to be a fair experience for every player involved, and knowing who you are playing is a part of that experience.
When you play versus 5 barcodes and you have no idea who they are, what their tendencies are, what builds they might use...but they see your account as "Liquid Snute," or "avilo,' or "Puck," these players can immediately have an information advantage just by knowing who you are in the community and what your tendencies are and what your range of builds are.
This is a huge deal. The solution and counter-argument should not be "just make a barcode as well!" because that is a ridiculous argument and doesnt' address the main point.
Barcode accounts are simply an unfair advantage because you maintain your anonymity while knowing who your opponent is. Would this scenario ever occur in a tournament bo3/bo5/boX? No. You might play an unknown player, but you at least know who they are and can look up VODS, etc. or get some information on them.
As a player/pro/ladder player...barcodes absolutely give an unfair advantage and i think it's time we discuss this as a community and hopefully get blizzard to get rid of these accounts. If people want to practice anonymously they can do custom games - a public ladder is not the place for having such an unfair advantage.
Now, i want to go to the streamer perspective.
As a streamer with a pretty good viewer base...this is a huge issue for me personally. I do not know how much it is for other streamers getting sniped, but every other game i'm playing versus a barcoded player sniping my stream.
It would already be bad enough playing versus barcodes normally, but then as a streamer when these people are purposely harrassing via barcodes over and over...how do i report these people or identify them to blizzard or twitch? There really is no winning here as the streamer in terms of putting an end to the harrassment from anonymous people on barcodes.
At least if i knew their ID, i would be able to metagame them as well. Simply put, it's everything a normal player experiences but amplified because streaming the game let's people snipe my stream anonymously for an even more ridiculously unfair advantage.
What do people think of this? I personally do not think the SC2 competitive ladder should allow for barcodes and something should finally be done about it.
The best analogy i can think of in relation to a standard username player playing versus a barcode player on the ladder is - you are basically playing a game of poker with part of your hand revealed to the barcode, but you cannot see his cards at all.
