The level of depth in gladiator fascinates me and has kept me coming back for many years. A good gladiator match on GunZ surpasses any type of battle in terms of fun I can have in any other single player or pvp experience just because it takes more skill than any other game I've played.
That's what I like. What I don't like is the play-to-win mindset of 99.99% of the community where they'll play as cheap as possible in order to get a kill. That and reload shot.
The freedom you have in the game provides the chance for so much it's difficult to state any one thing you like without being vague or incomplete.
What I love is the freedom of movement and attacking, much of which is thanks to k-style. In gladiator it really lets a person fight how THEY want to, rather than forcing them to fight one way to survive (kill fast, kill first).
But as previously mentioned the ego is the real killer. Too many people are obsessed with winning or don't get into the game and so barely have any fun playing it.
Some others are blinded by prejudice, whether it be a certain game type or a certain play style (turtle, flipping, side pedal ect are all under this category) and rather than learn how to deal with it, they complain, rage and just plain QQ. In that situation the one who wins is the "noob" doing the thing you hate, whether you beat them or not.
Whoever rages at the end of the match loses because they're not having fun.
