When you speak of prestige, there has to be something of Value to seek first in order for it to be valued as such. Like how it's prestige to get an Ultimate weapon (despite people paying for pilots to get theirs) or the prestige of getting <World-Class Troller> after a long grind. Maybe the prestige of collecting all of an expansion's relic weapons exists due to their looks or you want a full set for glam. for PVP what is there that isn't a title that will eventually have multiple people with the same thing on it? Overtime there will eventually be more and more PVP titles due to them all being the exact same. There is nothing different from a season 3 "Of the Final Conflict" title holder from a Season 5 "Of the Final Conflict" Title holder.
If they cared about this "Prestige" still, why has every 'season' best three rank titles been the same exact name? Where "Of the First and Final Conflict" or "Of the Fifth and Final Conflict"? No wait that would also fall into the issue I mentioned before of just slapping on a number to the same reward.
Look just keep handing trophies out for housing i'm sure those PVPers who earn them TOTALLY HAS A HOUSE SOMEWHERE :*)
