So basically i got a new MBP like 4 months ago for programming and stuff but nowadays i feel a bit bored sometimes, therefore feel like playing WoW, so was thinking to start again but stopped myself because of the thought that: 1.Will my battery life decrease? 2.Will my laptops life decrease? 3.Does the laptop get too hot while playing? Therefore any help will be appreciated. I know about the FPS drops issue but i think it will be fixed in a few days by the arrival of 10.6.5 and a new fix patch.
