SMN is squishy, you'll have a harder time to pull as many mobs in one pull than on other AoE jobs and i could be wrong but iirc last i tried my thundersparks couldn't oneshot escha #2 mobs, at least not without support.
however if you survive the pull and get thunderspark off stun/paralyze should keep ramuh alive long enough to get the second thunderspark off.
With a good self DT set (it's possible to cap DT without using any armor slots at all) and stoneskin and phalanx you can pull every mob at #2 just as well as any other job you just need gear to do it just like those other jobs, if you have a good pet mab set you can 1 shot all the mobs at #2. I usually pull with out a pet and once i have a huge train I summon ramuh and thunderspark. Bayaami robe is essential so you don't get interrupted when casting ramuh, also if you get Hippomenes socks, they have latent effect flee (Getting hit activates it they are from immanobugard unm). Pull with diaga but the cp at #2 sucks so idk if its even worth it honestly, I usually just do that for merits but on my server you can't do it at #2 anyways beacuse of all the bst bots. Also if they dont die in 1 blood pact just use shocksquall it should stun em all until your rage is back up. P.S don't forget a mollifier
