Yes! It is totally unfair. Those who joined last year became legendary members without the real effort and those who joined recently can't come even close to that rank. Merit system favorites the old members. If a newbie wants to reach legendary status he must comment for years and all his posts have to be amazing! Merit system is nonsense now, it should have been introduced from day 1.
I'm not entirely happy with the Merit system - I was just about to become a senior member, and won't now. However, the fact the system favours older members is surely the point? They're the people who have supported Bitcoin through it's development, not the Johnny-come-latelys who joined in November because they heard it was a get rich quick scheme.
