This covenant can be pretty fun at the level 30 range. High level Dark Souls PvP is fairly regulated - everyone has similar health, about the same stamina, and then a soft cap in one or two different attack-centric stats. Low level PvP is much different, with 'vigor' builds that soft-cap on health while using only simple starting weapons, and nobody uses nearly as many Weapon Arts (let alone the ones that decimate health bars). Most gank squads with a couple phantoms, the summons have only triple-digit health, if they even pass the 800 mark.
It's a completely different environment where rookies and vets mix together using much more basic equipment, and where fundamentals like zoning and positioning are used to overcome ganks rather than getting a good weapon arts combo. Just beware the twinks -- it's definitely possible for someone to come in with only a +3 weapon, but a +5 Estus Flask for some intense chugging.
