How berserking works: Berserking is a ppm based proc, similar to mongoose (1.2 ppm) - in a raid environment it has a ~35% uptime. It can only trigger off attacks flagged as melee attacks and melee specials (Judgements, CS, DS, white swings). Napkin math shows that in a scenario with a 35% uptime, the enchant is worth ~135AP on average, and up to/more than ~250AP if RNG favors you - in both normal and lucky cases, it is clearly the superior pve weapon enchant. The armor reduction debuff has also been reduced to 5% (from 25%) making this enchant superior for pvp as well.
Тут написано,что берсерк висит примерно 35% времени и в перещете на общее время дает примерно 250АП,что сильно лучше 135АП-ного энчанта,а уменьшение штрафа брони на 5% с 25% делает этот энчант лучшим как для ПВЕ так и для ПВП
