The Ice Queen boss at the end of a relatively fun run of the SL, post gunner update. http://youtu.be/le95NJFku_U
Definitely enjoying the higher chance to proc fire with pepperbox, Iron Slug destroys huge slimes, and mixmaster gets you into troubles with GM Atlanta (not included in video).
Normal mode kill speed on elite difficulty, yeup.
Was it on elite mode? I thought I saw someone in your party doing a shadow lair on my friends list, and it was easy mode. Could be wrong though.
IQ was never a hard boss at all, nor are the new guns more powerful than existing weapons, afaik. Grim Repeater = Blitz and Iron Slug should be roughly on par with a Brandish. Not really power creep.
Slug/Grave can hit more times than a Brandish, I think, and definitely do more damage. The only thing they don't have is the initial sword swing on the charge attack, which can do 1k+ dmg, but that's only if you're in melee range of your target.
9 radiants for all that... must be disappointing.
