There is already a shield for the Rus with the "Swastika", also with runic-like symbols. Maybe, as pointed out, they should have shields emphasizing their Orthodox Christianity - or just neutral shields without religious meanings.
Well, in any case I beleive a pagan Wendish faction is in order; not saying that it's a top priority - but with the help of the community, a thing to aspire to in my humble opinion.
Also, Slytacular: The Scandinavians wore the symbol of Thor, probably to oppose Christianity - very few amulets of the hammer has been found from before the 9th century;
this could be interpreted as the above, an opposition towards Christianity, (although they coexisted). Etc. etc.
