It doesn't actually take that large of a sample size to results to normalize. Let's see how the poll worked out.
DC Tycho (no votes)
I think Blood Angels players seem to understand the strength of the characters pretty well. DC Tycho really needs a boost to be considered again as viable. Everyone knows the Captain has weaknesses and no access to artificer armour. Dante, Seth, Lemartes and the Sanguinor are all weaker now in 6th Ed. The librarian is pretty much the default choice with access to psychic powers and ability to customize. Astaroth and Corbulo are relatively better compared most of the other special characters. Corbulo might almost be as an auto include as the librarian with the Feel No Pain rule.
