I'm not sure if that would really solve the issue, since a person can end up in a dungeon via leveling roulette and not be geared for the dungeon they get (the ilvl for leveling roulette must be the one for Sastsha after all)

That being said I do agree that this is an issue that needs some sort of a solution. This game is giving you pretty bad feedback on how you should gear up (...and how to play your class aswell...). I'd really like some sort of warning message for people not having proper gear, aswell as a good guide for them HOW to get gear. Some might be believe the only source are dungeons and just suppose they're being unlucky and that its fine to run around half naked.

Beside from euqiping gear there also has to be some guide in place telling them what kind of gear they should choose - I've seen so many melees running around with int-accessories, healers with strength, tanks with mind... Some might do their own research but apparently a lot dont, dont know how to get gear etc. etc.

What I'm saying is: Instead of blocking people from playing, give them better feedback and guidance. That shouldnt have to come only from us players. The game should "forcefully" tell you to gear the fuck up and tell you how to get your gear - NPC-vendors, marketboard, etc. We get one quest thats forcing you to gear up... after that... never again... Let checkboxes or something like that pop open when a player reaches certain levels - like 25, 30, 25, 45, 50... - that tell them "Hey, your ilvl should match your chara-level, check it out! If it doesnt: Go here -insert location of vendor for that level- or visit the marketboard in one of the cities to get better gear!" I feel making it easier for people to figure out that they should have to gear up and also how/where to do it would be better than just blocking them from dungeons
