You guys are living in candyland.
Yes i forgot about the shield part (i play more than 4 jobs in pvp and when i heal as astro my job is to double spam heal to save someone's butt, as they cling to last 10% of their HP bar). I use heals for my teammates not to shield myself. I will use double heal to save my friend that to *overheal* myself in case there is a stray samurai is in the bunch.
But you can not play around samurai. In the current meta i play around DRK premade or no DRK premade. Period. If samurais were a meta - sure. we would adapt and play around it being 101% HP. But instead i see my party being pulled in and oneshot (or nearly 1 shot) byt the so skillfull premade. SO i use my so valuable followup heal to save those who i can before they get finished off. Why? dunno. After a couple of those combos, even on the third team which we cant control at all (do not tell me to ambush the premade while they are busy with other team. it works 1 time out of 50), i face up a BH5 party with triple the ammount of scores. So there are 2 coises: try to do stuff as a honorable jesture and loose anyway, only to be blamed to not overheal myself (yes i forgot about the shield) against a lonely samurai in 20 people mess, or go afk in the spawn like 4 or 5 of your teammates did from the get-go.
And today i tried samurai for the first time in a year+. melee atatcks are potent, shield pierce is nice, but they are all so SLOW. i cast the ability and enemy ninja with 5% HP sprints away while my teammates are picking their nose. And LB is a chep shot. I killed like 5 without trying too much simply by waiting for LB and pressing 2 buttons. They didnt even attack me. And they died 100 to 0 through BH4
P.S. i denied 2 ninja LBs BS today with a last second recuperate. Thats what EVERYONE can do.
