In the Igloo Garage, as fast as possible...not really unsafe there. Mainshops, if you want to be on the safe side, try at least 3 seconds.
I set my minimum buy time for main shops to 1.6 or 1.7; I've never had any AB related freezings with those buy times. It depends on the shop as well though. When I (rarely) AB in magic, I set my minimum to 3 seconds.
Wow... isn't that like VERY fast..? I've heard from other people here that 3secs in any Mainshop is really dangerous. Edit: is an igloo AB buytime of 0.6 secs okay?
In main shops, anything around 3 seconds is kind of safe. In Igloo, buy times are just FFA, as fast as you can go. In Attic, buy times are just like the igloo.
Well I said I set my minimum to 1.6 or 1.7. Then I get whatever lag, and usually my buy times range from 1.8-5 seconds. I get stupid lag a lot cause my internet sucks, so I suppose with all the times I miss stuff it balances out. I dunno. Igloo is fine.
You get banned faster with 2 second buy times...that's what I usually set it to, but those I don't consider to be safe.
