I found that whilst soloing the ironclads or even Simmurgh that it was actually better to just go /war due to shadows being completely irrelevant and not lasting more than a couple of secs tops...
There may be a few other NM's that are similiar, where its a better option to just rely on your ability to cure yourself whilst beating the NM as fast is possible rather than out and out EVA soloing it, i know this was the case for me at least.
