No, NRZ was designed with the intent to create a sort of instant kill map, where most every shot removes the player from the fight entirely. I'd say that everyone can agree that it works that way.
In most FPS games, there are several weapons that outright kill a player, and that doesn't happen in SRB2. For CTF that makes SRB2 play very differently than most games because you can't generally outright kill your opponent. In NRZ that situation completely changes, as most shots WILL kill your opponent and running the flag is an insane challenge. Even I die constantly in NRZ.
The trick is to have different priorities when you play NRZ. It's not about living, it's not about collecting powerups, it's about getting your team a score and preventing their team from scoring. If there's a sniper annoying you remember that one rail shot is all it'll take to send that sniper into the abyss where he belongs, but if their flag carrier has made it back to their base, you've got much bigger problems.
