Thank you the disk-cleaning tips. It's always important have a clean disk. If you stick a dirty disk in a slot it can really mess things up. Cleaning a dirty slot is harder than you think and if you don't clean it soon after having a dirty disk in it you could have long-lasting problems.
No chance in hell blizz is worried about their player base, they've proven over and over they don't care at all, the service part makes the money so that's what they are doing, the sucmbags could at least be honest about it
