Highlights :
-Shadow refuge as a buff is very nice, it's easier to keep 100% uptime of it.
-Astrogha went from an immense pain to as easy as most others 125's.
-Shift clic barrier strike is amazing and make a few part of the game 5 time easier, noticably duncraig went from problematic to free. And yes, it's not in the note but barrier is included in the melee qol. It would have been kinda dramatic for the only melee attacker without melee devo to not have this change.
-Way of the raven improve elemental builds quite a bit ; ZKT, Black Ice, and even leveling with ways now went from a bad idea to something real good. Early leveling with
Blackleach Blade
makes sense now, this weapon easily carry to 125 without anything else. I really recommand it. It's more damage and better frames than physical, but obviously you're missing leech and the big defensive values of Na-Krul. However, the defensive gains from doing barrier strike with shift clic compensate that defensive problem, that would have been painful when farming before. Ele also come with another good point that you're not dependent on dex for damage overall, so you actually can invest in str nicely early, and vit later. Dex is just for AR.

-Queen of blades proc is stronger but still not worth to put points in.
-Nagi breakpoints got a bit better, ~138 IAS will be enough for 7 fpa (from 163) (I don't know the exact value, except that it's higher than 128 and 138 or less). Anyway, it's much less painful to get that breakpoint now.
Very nice changes overall
