But other classes that were deemed to be OP were nerfed within a couple weeks. Not months down the line.
This is false...
1. Many classes that were considered OP by the "majority" in the past have gone much longer than a couple weeks without change.
2. If I'm not mistaken, jugs got the buff in 1.6 which released December 5th... so technically we have not reached "months down the line".
