I would really like for this game to have a special survival mode. Form a light or full party. Enter an arena suited for your level (like PVP) at level 30, 40, 50 random and 50 premade. Fight like in T4 against mobs. You have a minute before second wave and so on. Mobs get harder and harder and harder and so on. Doesn't stop until you die. A lot of older video games had something like this, and this totally should, seeing as it seems to fit this game well. It can drop exp, Gil, tomes, and random items/gear depending on how much you survive. 50 Gil per wave (at wave ten it becomes 100, at wave 20 200, and so on) exp per mob, 10 philo tomes per wave, 1 myth per five waves, HQ items every ten waves, gear dependant on wave as well, potentially some BiS gear too.
Thoughts?
