I managed to clear Hudson Refugee and Lex challenging on the PTS with minimal changes to my current 1.5 HE build. I had to roll health on everything that can take it, coming in just under 400k toughness. With tweaks to mods I could get this to 400k. With the nerf to seeker and flame turrets the ability to damage and control the mobs is quite difficult. The roof section of Lex took me around 12 attempts to clear. The sniper takes me down to 1 bar and then being anywhere near an explosion at the same time would wipe me out. TTK was Ok but TTBK seems much shorter.

Skills
Strike Back - brings the skills back quicker when needed
Tech Support - extends the skills ( did work well for turret, but now...)
Tac Advance - I spend a lot of time in cover with Robust and Nimble, so it works well for extra damage
Chain Reaction- more explosive damage, more healing through relentless , plus controls the mobs better
Armour mitigation 31.2%
DtoE +35%
EAD + 57%
I really noticed the lack of punch in the turret and seekers, it was easier to be overwhelmed especially on the roof of Lex and the balcony in Hudson.
I thought I was playing the version of the game Massive wants us to play - I spend a lot of time in cover and shoot a lot - but the changes have just made it more difficult. The latest I read is that because everyone is spamming Nimble in Last Stand now, it is the next likely to be nerfed.
Nobody cared about Nimble, even after it was fixed in 1.4. Now because of one you tuber who used it to revive from death ( I must say, that's never happened for me) it's going to be nerfed. None of my PVE opponents have ever complained about me using Nimble.
