If anything they would just upgrade it to idtech 5.. Carmack once talked about giving quake live a "spit shine", however nothing ever became of it (he's definitely too busy).
No? It doesn't happen to me or anyone else I know.You would be very ignorant if u havent noticed the fluctuating damage control, where players sometimes get killed by far below what normal. Other times You can pound lots of rockets direct on a player without killing him.
If you find such a discrepancy, _demo_ it. That will prove that it happened and a bug fix can be worked on. Personal testimony is not good evidence, especially when it is so contrary to what other people experience.
Extraordinary claims require extraordinary evidence.And I have even myself (sometimes and rarely) killed full health players by single shots.
