You probably not like the patch then... I certainly didn't have lower level mods and had issues. Seems like I needed a 20% boost in skill power to get back into my mods but I think my skill power was at most around 2700.
It actually wasn't that bad. I had to juggle a bunch of talents & mods and recal some stats but I got my stuff up and running. Still feels cobbled together but I ran some challenging missions and mostly did fine. I went from 10s cool down to 15s but my damage went up and with cool down affecting talents, it's workable. I think once I get some more gear, I'll be doing better than I was in TU5. I'm running the new Technician specialization but only unlocked the skill boost and +damage against bots. The +SP is enough though that I'm over 3k on both and trying to adjust for more skill haste -- and I haven't unlocked all the +power boosts yet.
My AR build and Pistol build largely received straight upgrades since neither depended on skill power or stacking talents. I did get the Unstoppable Force nerf though but didn't feel it much.
Targeted loot feels really nice and I think will help people a lot. Expanded name sets are also nice. Between the two, I might be able to get a third RK piece for the +Shield power on my pistol girl. Carbine 7 went from trash to being pretty sweet; glad I kept mine. Haven't played the new Pentagon mission but did the two new Classified missions. Overall, I think TU6 will be very positive for most players.
