u made multiple mistake on ur rage cry
1. u can wait 60 min. to kill glas and still get rank but it wont be visible unless sum1 check u ( it is impossible to solo glass legit, if sum1 check u ur doom)
2. u cant breakoff glas solo, nexon did this to prevent hackers
3. if it's dirt cheap then buy it dont cry about it
4. try playing without hacking for once and u'll see how enjoyable the game is
