We don't hand out warnings or bans for asking about/mentioning developers in the forums (so long as you're not sharing their contact details, harassing them or insulting them). Mostly bugging them in private can mean trouble. Or getting others to do so.
As for the suggestion, we've added so many features over the last year for non-spending players... The game got multiple guaranteed mythicals now, lots of chances for mythicals, the crafting system and the survey system. i'd say we've been quite busy on that end.

On the other one, to put it simple the rewards for a top rank are prizes... They're giving for achieving a particularly good rank. We could also award the top 6. Or the top 20. Or the top 100. Or everyone really... but it's a competitive game. We have to put a limit somewhere on what ranks make the cuts and what ones don't. Top 3 is pretty standard...
We may consider other numbers in the future but yeah... If it's top 6 I am sure the #10 will complain we don't round it to a nice top 10... Never ending story there.
I'd suggest being happy with achieving so much - beating so many other players and focusing on improving as much as possible. There's always room for a new top dog. Don't need to spend anything for that.
