The reason FFXIV raids are designed in this way is because trash mobs pose no benefit to anything int he game. They are useless to implement as many will just find ways to skip them to get into the boss battle. This allows us to get straight into the fights with having to waste time killign the same mobs over and over. 24 man designs are more raidlike however the more people you add to a fight the harder it is to tune its difficulty because you dont want 1 person to wipe 24 people (and it still happens in the 24 mans). I would like to see a 16 man mid tier raid seperate for 24mans easier tier and savages 8 man slug fest. Also the game desperately needs to add random drops from mobs in the overworld and in the dungeons. Its always exciting to see shiny stuff just get added to your inventory. RMT won't matter because it already happens and might they always find a way.
