I agree the taxiway layout is pretty complex in that spot (Twy's Charlie-2, Bravo-4, Dom-2, Charlie, Golf for anyone who isn't sure of where we mean, see attached pics), and I know it's an area that's fairly well tested for people getting taxiway driving authority's.
If you had the option of changing it from it's 2010 layout Mick, what would you have suggested?
