She does not mean PvP rewards, as in the stuff you get for the tokens. She means ranking rewards gotten at the end of Feast for those that have the most points. Those are exclusive. You cannot get them once the season ends. And only X people can get them, depending on the reward. Very few X people. Look
here.
The trophy is pretty obvious. I mean, you shouldn't get a trophy if you're not the best, right?! I personally have no issue with an exclusive TROPHY for being the best. Maybe some sort of medal as an accessory for those lower on the rankings and/or for meeting the specific rank (I mean gold, diamond and what not). But when rewards include MINIONS and MOUNTS, both of which are collectables in this game, and glamour, which is the most popular "end-game" stuff to do for many casual players, really, it stops being fine with me and apparently Itswhateverthough.
