You cannot properly do your part with a level 50 i110 weapon in level 60 end game content. Not sure why I would have to repeat this fact at this point in the thread.
No....I've basically shown that it is a problem with that in progress run with the BLM in my original post and also the testing I did.
The group wiped (possibly multiple times) before people ditched and DF eventually replaced half the group with people who could carry this player's low DPS due to the BLM's massively improper weapon. So not only did he waste his own time; he wasted the time of up to 11+ other players (the party was half missing when I joined). I believe the DF itself shouldn't let that happen.
As soon as you argue that "it is not a problem because the game let him queue" then...that means I could dress my tank in the full i150 crafter gear and queue for ARF/Fractal/Neverreap and no one should have any problem with it even though I won't be able to actually tank or do my job. Still no problem?
This is the gear I could wear on my tank and still queue:

To top all this off I could even equip healing accessories to go with this crafting gear and still queue so I would have almost no VIT and no STR.
This is just an example and it isn't really end game content (more like entry level end game) but it is basically an example showing you that the game might let you queue but obviously there are times when it shouldn't (just like my original post) and that it is a problem whether you want to accept it or not.
This is seriously not a problem that I am there in that state because the game let me queue? If you still think that then I don't know what to say.
