Is this arguement still going? You don't just go in a dungeon all willy nilly. You have time to check your gear well in advance and granted, the gear could still break in a dungeon but the only time that has ever happened was when a group could not handle a trial.

Honestly if you go into a dungeon with low durable gear it's you're own fault. Why this is an arguement right now I'll never know.

The counter arguement of the gil payment isn't even valid either because repairing full sets of gear from 0 costs basically nothing to begin with. It just sounds like a lazy excuse for not being ready for something you que for.
