"Trash" is worth killing because you want to get to the Boss. Boss is worth killing because you want some loot. I can't get onboard with people wanting something for nothing, the very same people that call non Boss mobs "Trash" more often than not want these same mobs to drop what the bosses drop (although with more rarity). These are not time sinks they are part of the overall makeup and experience of said dungeon, the entire game itself is a time sink.

On another note, I've no sympathy for people complaining about lack of end game content. The game has just released, much more to come. I'm 50PLD and now levelling a DD and Healer Job too, plus Mining and Goldsmith, Doing Logs, Achievements, Minion Collection. The list goes on. As a hobby developer I can see why SE don't focus on people that have the time to play so much they get to Coil in 3 weeks and want more, you are in the minority and it doesn't make financial sense to accommodate you right from launch.
