Isn't that a lovely username!
TW/Sr is a good combo and the 1st attack boosts your melee defense. The reason you see so many ELAs and WPs (as I see too) is because people are scared of TW's endurance costs. But they're not that bad from what I've seen with friends using other armors and can work perfectly with Sr.
It should work, but it may call for quite an investment. My StJ/SR didn't become anything like end stable before Physical Perfection, and that was with endurance-light slotting and every endurance recovery measure short of the panacea proc. So you will likely have to go very light on the Obliteration sets.
But it TW works as well at decent recharge as StJ does, you're in for a great ride when you're done and a not at all painful leveling experience.
I've seen so many scraps with TW all have the same secondary WP or ELA and I was just wondering was anyone else running SR I've only seen two or three so far and just was wondering if anyone else had one or what are your thoughts on the combo. Also sorry if this comes off oddly written I'm sleepy and typing this, But if I don't do it now I'll forget again
