- the best you can get from the mobs is a small crafting material you may need
Now you're full of shit and it's obvious you haven't gotten to the lv 70-80 range in Vindictus. Sure bosses drop the meat of the materials you need for crafting, but what about the massive number of ores and leathers you need in conjunction? That's where the trash mobs come in, and thus, they STILL drop worthwhile items. It's funny because this is a Korean MMO known for being grindy and at least they got that part correct.

In short, no, it is you who is full of shit.
