It would be nice a get something like a relic that gives advantage to the owner or faction, sure, but it would be too hard to balance it, especially as we have many timezones in the playerbase. Let's say US players get the relic, they can bring it every 3 days with no enemies online. One possible thing would be "the relic can't leave the core", you have to let it in a zone controlled by your faction.
It could be carried a bit like the flags, but you can carry it more time maybe. To get bonuses you have to put it on a specific area in whatever zone you choose, so everyone can check for this. It should be seen from everywhere (like a ZC message). Could be a nice way to make people use more traps, even sneaks would have more versatile jobs.
And make it a slight bonus, not so important so people would rather ZC or do both than just chase relics. And when it's small scale pvp, it can make people gather at the same place
But yeah, as said above, not a GECK please, just another relic !!!
