Lol - I've been playing WoW and I still didn't understand

Don't worry me like farnk yes!
In simple terms, in world PvP it's still all about stats and enchants. But in instanced PvP (iPvP) its all about gear level. Basically everyone gets the same stats depending on class and spec, whether ur gear is good or not. But if u lift ur ilvl high enough u start to get increased stats. It's a big difference at higher levels but at lower levels is only minor.
As an example of how minor, I can only talk for 20's though 29's are similar. Standard ilvl at 20 is ilvl 25. If u can push ur ilvl up to say about 33 or 34 u start to notice +1 to some stats like stam, ag / str / int and armour. Now if u can get up to say ilvl 40 u will get some stats +2 and so on.
Weapon speed also plays a role. As far as I'm aware the slower the weapon for some classes the harder ur attacks.
So look for ilvl and slow weapons and u'll be slightly ahead of the pack. That's why u have been seeing some white items, it's because of the ilvl of the item.
Edit - forgot to mention u need to fill all ur gear slots and they need to be the armour type of ur class also. If u miss slots or u have wrong armour type it'll dramatically drop ur stats.
