It could be created a system that would give a player a weapon that could log for example 30 days in a row (for harec for example) plus another weapon adding 45 consecutive days (example: valeria), this would increase the frequency of players in the game and would stimulate commitment and dedication in a fun and different way.
A weapon that would be impossible to buy would only be acquired by dedicated players who strive to maintain a large, united community for a single purpose.
