the thing is people jsut dont do arena that much, they do their daily's and stop. It would be impossible to for them to match people based on ninja stars. Once u get that high in rank u will only get someone if they have waited for like 5 mins. I had to queue my second account vs myself casue no one does arena....

Exactly, i do my daily get my coins done and thats all. After getting six path there is nothing to do in arena, sometimes soem group mates queue up to test our teams when even but thats it
