About threat system, Its not hard to think about some ways like.... week ou month treath system, players play for one month/week and based on her statistics, like match win, kills and other things, for next month/week he gain an threat based on this and this threat cant change until next month/week and this change still based on last month/week statistcs, and at last make districts with treath lock, golds can only enter on gold district, silvers on silver, and bronzes on bronze, with this two things at last you can save silvers face gold tryhards and bronzes from silvers dethreaters at last for 2 weeks per month or 6 months per year.
