You get 1 token at the end of the Season for being in Top 100. You get two for Top 10 and three for #1.
There's a token shop where jewelry costs 1 token, gear and mount costs two and a crown, minion or something else costs three. Some items like #1 housing trophy will still be exclusive to winners.
It'll solve many problems, like exclusive mounts being unavailable to new players later or to those who can't make a premade team on small server and grind into Top 30 for a premade mount; they'll just get it through alternate means like being in solo Top 100 for two seasons.
