Also. We do not use LB during the the tornado add phase. We clear it raw damage and use caster LB3 later.
On another note, here's my 4 minutes single target on dummy;
4 Minutes dummy parse
Please take note that extra 3 seconds happened because I had a thunder DoT left, I was at 1300 DPS. This is no party, Draconian Potion + Creme Brulee.
This is the gear I was using;

I got blessed with loots but it's pretty unoptimized. I don't cap my food stats and my spell speed is very low. I don't think you can see a SMN dull those numbers week 2 of Alexander Savage with that gear. 1300 Single Target DPS is melee single target DPS. I also do not Lethargy adds, I could to help but it's not needed. That's how much DPS we have to clear the adds and I'll be honest, if you need Miasma II and Miasma from SMN to slow adds, you probably don't have the DPS to clear this fight to begin with.
I'm curious how Summoner pulls on a dummy actually to see the difference. Summoner is definitely easier to play in A3S I completely agree on that however :p
