Resolve over force wielder? That's definitely weird lol.
Not really. Endurance isn't really that needed once you get over 25k health. More WP gives you more damage output which is great for threat management when you're teamed with well geared people. I ran a resolve hilt as soon as I could have one crafted. Recently switched to Force Wielder (was a gift from a friend) and then proceeded to upgrade my DPS gear - hilt and all armorings with high willpower went to Nadia and I've replaced them all with high endurance stuff.
I'm currently sitting at about 28k health but that's just because I can't be bothered to replace my lettered mods with unlettered ones. There aren't many on the GTN and I'd rather gear up some other characters too. The only thing I'm after right now is the DG clickable relic to be used in boss figths. EWH is okay for general mischief, but what kills tanks is spike damage, so a clickable relic will prove more valuable in boss fights.
All that said, I've pushed my health (with stims) to 29.7k and still got no protests from my dedicated healers. We've been breezing through content with me having 23, 25, 27 and 29k health.
