How is ilvl an issue while leveling?

[Nestama]

Most expert dungeons have a minilvl that's 20 ilvl below what the dungeon drops. For castrum, that would put the min ilvl right around 270. It's fine.

I find it it funny that everyone complains how easy the game is, yet expects everyone to overgear everything to make sure it's easy.

I feel the minimal ilevel for Castrum Abania would/should be around i276. You need to take level into consideration as well, as the difference in defence between an i270 body piece and i288 body piece is pretty big (388) compared to an i310 and i325 piece (~38). You shouldn't say "it's fine" without following up with "highly not recommended" as that, to me, looks like you're enabling bad teamwork. It's forcing everyone else around that player to adjust to them alone.

And really? Level 68-69 gear is overgearing a level 69 dungeon?
