Yup there are a lot of things about duelmasters that I really liked, perma death till you got out of the basic arenas, the large number of fighting classes, lower stat range for glads (3-21), non-magic gear (which made your glads stats SO much more important).

Yup, i keep hoping that one day Nate will give us a Hardcore arena. With some simple rules like:

1. Glad dies they are gone.
2. No HOL Slaves
3. Limited gear. (maybe even whites and greys only to lower the kill rate some)
4. Faster glad learning (say double the current training points per day).
5. Retirement allowed at 1k fights like normal (gives HOL slave in regular arena, if you make it).

Then run some kinda tourney quarterly, where the dead glads get a chance to come back, just in case someone looses someone cool

I'd be all over that
