Pretty much. You can count on the ones at top always being those that pay. As a freemium player it is better to just try your best, hope you get a decent rank and then be happy with what you got. I'm a freemium player and i'm at rank 202 in the list at the moment, which still keeps baffling me as i was 500-1k somewhere in the start.

Also within the top 50 in support

Edit:
Somewhat mixed feelings about the event being over soon. On one hand i will be back to 7+ stamina rolls, on the other hand i will be back to 7+ stamina rolls! It is a blessing when doing quests, but it takes eons when i want to quickly roll off all my stamina so i can do something else -_-
