My issue was you claiming "if the game lets you enter it's not a problem". Which is why I posted that example in my last post, which you didn't comment on for some reason, about Queueing as a tank for level 60 dungeons with full crafting gear and healing accessories on.

This is a tank queueing for a dungeon wearing all crafting gear and healing accessories and level 50 weapon going into level 60 content. The game let me do it. So I guess it isn't a problem?
Again, as soon as you say that it isn't a problem because the game let them queue then what I just did in that screenshot is 100% no problem at all. That's why you just cannot support that kind of reasoning because in the end you just turn into a hypocrite. Anyone who plays this game knows that screenshot is a serious problem. (btw I have less VIT than a level 40 something tank)
