Would like to know popular mmos where the gear you get is what defines how strong you are. Games MUST have pvp. Please list what you know!

edit:
i know every mmo gear is crucial but, for example, games like guild wars 2 is more based on skill of player considering "end game gear" is very easy to come across. I guess the feature they will have in albion online with how strong your character is, is more along the lines of what i'm looking for!
