Need some help identifying this cool game my friend told me about(he forgot the name). Will you help me?

Details- It is a online mmorpg, featuring a modern medieval clash. You can only create a human, no dwarfs or orcs or any of the sort. It is a 3d game, controlling your player with w a s d keys. There are water features, as being able to swim under water, or take a boat ride. The different servers are called realms. There is no cd required, though my friend does not remember if he had to download it or not. You have some sorta modern and medieval bar, that shows how much modern or medieval you are. If your more modern and use a medieval weapon, the stats will be decreased, same with medieval using modern stuff. The more you turn with modern stuff the more your modern bar will go up, and medieval go down, or if with medieval stuff medieval go up modern go down. You can get your main lvl up to lvl 85, and all the individual lvls up to 100 each. There are alot of pvp features, and my friend told me he saw many airplane battles. He saw people with dragons, and this one guy with 6 tanks behind him. He said each person could own up 6 pets/ machines, like dragons and tanks, but thats for the high lvl players. He said it was free to play, but you could buy benifits. He said the benifits were bought in packets. For example he said one packet was you get to explore more land, another packet is you get to use more weapons. He said each packet cost about $20.

Closing- Overall, that sounds like a realy fun game to me. If you know what the name of this game is called plz post below(saying the name, a link could be nice). Well thankyou all for trying.
