I think a Repair button would be a nice add to the gamelauncher since not everyone is reading these forums that have connection or crashing problems and i also still see loads of people that do visit the forum and are having problems with connecting or crashing alot.And they usually don’t even know about the -Repair command at all.Anyway,its pretty common for most mmo’s to have a Verify gamefiles or repair button on their gamelauncher,it’s basic stuff not being implemented after over a year release.
Also it will keep your tech support section a bit cleaner perhaps.
