I think with a little work to a lot of work, gladiators could be popular. Since the feature was put in, just never really fully implemented. There just needs to be a purpose behind using them. Such as ability to earn tradepoints, award points, tokens, gold, something with your main characters. Ideally I'd see gladiators working as, you as a player enter the gladiator arena. Maybe there is a way to have two separate characters that are joined persay. So you can either only be logged in on your gladiator of that name or your main character. If a pk leaderboard is established, it could also be applied to gladiators. I think gladiators just need a bit more mana, moves, hp on par with what the classes currently have etc, and perhaps even be GM, while we have that feature, so we can truly get a feel of where classes need to be balanced. Perhaps have the gladiators the ability to earn tradepoints themselves and have more purchaseable items only they can use, to get gear equivalent to that of what the classes can attain on the outside which further helps in balancing. For now I think all there needs to be is some scaling of the current gladiators remorts, which will in turn affect moves, mana, and hp, and some equipment given to the gladiators. With perhaps the ability for that equipment to be purchaseable down the road. Start implementing the pk systems there, as a test area basis, and then branch out. Just a suggestion, it's all already there, and will be balanced and fair and maybe people will want to get involved in pk that normally don't because it should be a level playing field assuming our classes are balanced.
