TBH, the Rogue wasn't doing too much work there, because while I did get lucky with the drops, I was playing an orc, and this is doable with halflings (not sure about SMM, but most others are).
Thing is - when you stack the dodge boon on the starting 20%, then your quicksilvers are almost guaranteed dodges. What's even better, if you prep Namtar's ward, and find say Cydstep and the Badge, you can get a bunch (well 2-3) natural dodges off DP hit attempts. If you find Cydstep and Dracul it gets silly(er).
And, well, the starting damage bonus is a big deal in that it managed to soak up the JJ desecration penalty, but yeah, it's probably doable with a berserker and a warlord. But again - I saw this work without orcs or the trisword so many times, that I see this particular run as "too smooth".
Nevertheless - is this sort of thing required? I mean, if the Rogue is this powerful, and I wasn't playing all that good or bright and I could've gone easier on the preps (it's doable faithless depending on the boss, and it's also doable without locker preps), but if lvl1 is enough to kill a boss that is supposed to have an advantage over you - could the rogue stand to be adjusted a bit and not become "worthless"? I mean, if lvling up to lvl2 can be seen as overkill, then maybe the class is too good even for a newbie crutch?
(also, I agree with just about all q3 said)
