Orc and gladiator are very good colors in my opinion. Orc is a pure green color, and looks strong in some sets. Gladiator is a solid color, looking good with many things because of its neutral look. I personally enjoy gladiator more, but they are both good.
If orc was more expensive and just came out with the name 'jungle', people would like it more, and it wouldn't be over-used.
If gladiator was more expensive and as a promo(gladiator is already a good name, heh), than it would be popular.
Obviously, people think these colors are shit because of them being over-used.
