The fount buff was there. But it's like the scaling of spells just wasn't enough to damage the names sufficiently. Even the AA-based spells which should have hit much harder than the apprentice spells were barely doing anything. I can't really explain it but I totally understand how some people might think this is not soloable, at least with some toons. My SK in similar gear but with expert spells could kill the names in a couple of minutes. Aside from the zerker there was at least one other toon that needed help finishing the solo. Anyway, my point is there's some validity to the OP's bug report, even if it's not experienced by everybody.
