Over at EUQL there is an interview with the professional FPS player United Kingdom Gareth "GaRpY" Marshall from the Multiplay i36 tournament in the UK. They talk about Quake Live and switching from Painkiller, among many other things!
EUQL: A number of people are asking for certain weapon damage to be altered, namely the LG and the RG, is there anything you would personally like to see changed in respect to weapon balance or do you think things are working well as it stands?
GaRpY: I actually like how the weapons are balanced at the moment; I have recently just started playing quake3 and omg!! the LG and Rail are like quad all the time… so powerful! I actually think Quakelive has got a nice balance to it as it stands.
