What is the point to playing Arena Hard Mode?

[Anavel Gato]

After the 1st run, we already get the Legendary Weapon from the Boss, what's the point of replay the tournament if there is no reward in it?

For people who wants to experience it again.
With a different party composition and setup.

The reward is the cash, you honestly think they would keep dropping legendary?
It is simply like the rest, replayability so if you don't feel like world map battles.
To then do some Arena's for gold.

You also get a title for doing each hard arena. You get a permanent boost/buff.
