You can play on other server if you want you just need to open your wow folder (5 seconds) and click uninstall (2 seconds) can do it while changing your realmlist, since you gotta do that anyways. (you could use multiple clients or even shortcut the uninstall and install onto your desktop, and take it on and off freely, its an extremly quick install / uninstall)

it also wont make a difference to your comp lagging, you wouldn't even notice the difference it's so minimal.

press start run and type in cmd minimize the box that pops up and start wow, thats what it would be like, and you will notice there really is no difference in your pc performance.

(denmmo.exe memory useage is 140,000 bytes, thats what 0.01% on 128mb of ram, 0.005% on 256mb of ram, 0.0025% on 512mb of ram and cpu usage shows up as 0.001% with a 1.8ghz processor, 0.0006% on a 2.8ghz processor)
