it looks good, but just a few suggestions.... and whether you agree is up to you, i just think that these might help :P
i would get rid of all those points in imp. heroic strike, and either throw them into +1% parry or into Tactical Mastery, the latter especially if you plan to go between arms/zerk stance.
i dont think imp. charge is all that great, just imo.
also, Flurry in the fury tree isnt truely that great. 30% + attck speed for 3 strikes doesnt seem all that great; those 5 points could be spent better elsewhere.
well other than that, i think its a good tree. interesting, combining the two trees for DW swords
