GW2 has no "Horizontal System"
Berserker gear is the best gear due to the kind of content it is.
Horizontal System doesn't work without roles. So - no, its not a game we want.
Horizontal System shouldn't be balanced, it should be around the kind of playstyle you want. However this is a PvE game - Does Bahamut suddenly go on the forums and care about who has a bigger advantage in stats or crunched a bit better? Lol.
Anyways.

This is a perfect example of fun Horizontal Progression gear.
