Ah okay. Well if you've just got UT relics to compare to then I understand your statement better.
Threewave/RealCTF tech/relics consist of exactly four different type pickups: Haste (weapons fire rate - not insane running speeds), Regen (a small amount of health regeneration), Defense (less damage), and Amp (weapons damage more).
Each map has only ONE of each of these, spawned randomly. This initially encourages everyone to spread out to find them, as controlling them can give your team a bit of an advantage if used correctly. If you are carrying tech and are killed, you drop the tech/relic and your killer is rewarded.
The thing about them is this: by being aggressive with them you have an advantage in power, but you also risk losing them to the other team. By being defensive with them, you can't really score - can you?
It really gives an incentive to be aggressive, but not suicidal. It rewards smart team play. No one relic is so powerful on its own that having it would make you untouchable. But if you coordinate with your team, you have a pretty decent advantage. And of course, you can pass them back and forth to your team mate just as you would a weapon.
I'd love to see something like this as an option (or at least a mutator from some clever modder).
