Alright folks, you should know you have to monitor arenas far, far better than you are doing.

Explain to me the following:

Athenodoros:

-No plant life
-PermaRain, which can only be altered with the help of the weather rocks
-Dig users hit by Surf
-Fly/Bounce/Sky Drop users/victims (in the case of Sky Drop) take 5 Ice Damage, adjusted for type
-Ice-type Stealth Rock
-Electric attacks suffer -5 Base Power while the rain is up, and -2 otherwise.

The italicized here are fine in my estimation considering it's a water-based arena. The bolded are ridiculous.

Water is the largest type in the game. There are no less than 7 Fully Evolved Water types completely immune to Electric (Seaking, Quagsire, Lanturn, Swampert, Whiscash, Gastrodon, and Seismitoad) and several more neutral to it which just happen to be asskickin' in Rain (Kingdra, Ludicolo, Wash Rotom). The idea you can counterteam Water is nuts.

dogfish44:

- Electricity in the sand means that electric types are always under the effect of charge.
- The sand reduces the BP of Seismic attacks by 3, and gives Dig a -3 Priority to tunnel down, and -4 to surface.
- Attacks which require natural sunlight cannot work.
- Attacks which cannot work in an artificial environment do work, but paralyse the user 5% of the time as if hit by Thunder Wave, since the "Nature" is electric.
- Nature Power is treated as Shock Wave.
- There is a constant rainfall in the arena, which is unchangable.
- Mud Sport is washed away at the end of each round.

The vast majority of this stuff is fine, but given the fact every Electric has access to Magnet Rise bar Lanturn which does just fine in rain, Electric types really don't need to have +3 BAP -- Acc Thunders with constant +1 SpD, especially when their only natural weakness is equally nerfed.

Engineer Pikachu:

If you want to make Chills like Regenerator with the +6 HP fine, but axe the +6 EN. The rest of the arena is quite balanced.

Kaxtar:

This one seems the most balanced. A little busy but not much bad.

C$FP:

Constant Shrapnel weather (2 DPA on anything that isn't part Steel)
Steel types have constant Magnet Rise effect
Sandstorm and Rain may occur in addition to the Shrapnel, but no Hail or Sun
Dig can only be used by Steel mons (and Ground mons by virtue of STAB description
BAP of Fire attacks reduced by 3

One of the two bolded things should go, your choice. Magnet Rise isn't as powerful as it is in-game, but it's still plenty strong.

Korski:

Pretty complicated, but not unbalanced.

In any case, you should as a committee know you can't just eliminate all the type weaknesses of your Gym through arena effects. I trust you to monitor this in the future and not allow such blatant weakness lowering in the future.
