Actually, there are a multitude of reasons someone may need to re-install WoW. For instance I may have wow installed on my computer at home, but would also like to be able to play at a friend or families house as well.
Often times natural disasters could also require a user to re-install. Examples include power failures leading to wow errors, hurricanes, tornadoes, floods, lightning, godzilla, high winds, snow.
Also, related to natural disaster, are unexpected circumstances. A robber may successfully thieve your computer, or he may inadvertently knock the computer over, crashing it to the floor, while he and you battle for victory.
Other concerns include system crashes, viruses, malware, trojans, unexpected conflicts between wow and possibly another program.
Needless to say, there are actually multiple reasons a user may need to re-install WoW. I believe I have experienced 5 of the mentioned scenarios above.
Personally, my reasoning for compiling the 4 cds into 1 dvd also produces advantageous results.
Firstly, I really have had to re-install multiple times, and I must say that it is an arduous install process. On average, I would say the complete installation for the original World of Warcraft is roughly 45-55 minutes (4 cd method). I am not completely sure because I have never formally timed it. Nevertheless, it is not like simply downloading an instant messenger, a random web browser, or an itunes.
You end up having 3 additional prompts. I know many people will choose to surf the web, play other video games, or some other computer related activity during the installation process. However, some people will decide that the precious time during this installation could be diverted to something else (non-computer related).
In conclusion, it really all comes down to a convenience issue. One must also keep in mind the fact that WoW will be releasing content patches as well as full expansion sets, all of which must be installed.
WoW: The Burning Crusade comes standard with 3 cds to install with including another install time of roughly 45 minutes for me. Also, factor in the latest expansion set, and yall probably get the point now.
I was just paroosing around the idea of creating that 1 dvd for each expansion and found this forum. I decided I would register with these forums and make this post to enlighten yall while my wow fully re-installs after a system crash lol. It really isn't a bad idea considering someones frequency of re-installing. Sometimes it relates to performance or technical issues and sometimes it relates to GODZILLLA!!!!!!!!!!!
