Idea = ok
Implementation needs changes.
Now, this place being the only large fairly competitive combat server, this could not only benefit us, but could result in us getting a large competitive 1.9+ playerbase which is kinda cool.
Ranked duels should only have one or two kits and should support all fighting styles.
How about this-
One gap
Food
A sheild
Full (protection 1) iron
Diamond sword
Diamond axe
10 Arrows
A bow
Lava bucket
Watet bucket, splash water bottles
Blocks, preferably wool so we can include efficiency 3 shears.
This ELO would depend solely on this kit.
