Guild Wars 2

hello,
im lvl 80 berserker armor with divinity rune
and trinkets are orichalcum berserker ruby
i used this build in heart of the mist (pvp)
and there i have more hp? i did not look at the other stats, since i dont know the game mechanics but,
the pvp berserker amulet and jewel have vitality
where did the vitality come from?
right now i have 18.9k with 30 alchemist, without it ill have 3k less, in heart of the mist with alchemist, i have around 21-22k hp
so what build should i do?
i feel so squishy, when i was around lvl 70 with carrion i had more hp (in wvw) than i do now
Please help, im confused, spend 2weeks getting full set, altho im willing to change sets

ps. im gonna change my traits, for wvw battle
when i was 70, i only did the jumping puzzles with friends, but im gonna do battles and play wvw for the “first time” so probably my hp will decrease more, thats why im concerned

sPvP armor isn’t the same as PvE armor. In sPvP, Berserker gear allocates some of your stats for vitality (at the expense of crit damage). In PvE, Berserker gear only has Power/Precision/Prowess. If you use all Berserker gear in PvE, you essentially add no vitality to your stats.

Personally, I mix in a few pieces of Power/Vitality/Toughness (Soldier) and Power/Vitality/Prowess (Valkyrie) in order to boost my HP up to an acceptable level. What survivability stats you stack comes down to personal preference. Personally, I find having 20k health and 2.3k armor seems to hit the sweet spot for survivability, while still maintaining 40% crit and 52% crit damage.
