No they did not, did you even read what I said? People are able to queue in wrong gear for anything under level 69, basically a dungeon you gain exp for. you can gear in a level 1 weapon and sub level 50 crafter gear and queue for castrum abania. You can queue for current expert, just as long as the right side carries the left to meet the ilevel requirements. They did NOTHING to FIX OR ADDRESS THIS! The only reason for the class lock was to stop tanks using str jewelry. When doing that change, they did not bring up concepts of people cheesing the duty finder walls.
See? I did this just now, no SB did not address this. The ONLY reason for that change for the right was because of tanks wearing STR gear. Even with that, tanks still used i270 right to get around that. They made another change putting some str on tank right so they stop doing it.
Those changes had nothing to do with the NA player base cheesing requirements, just they did not want tanks wearing str right because it made things harder on healers, that is the only reason they did those changes, and that is why it was never addressed because my guess it is a NA player base issue, and they tend to ignore those.
