Yea I don't even use Fallen Sword on my hammerdin due to the crappy animation. You do have to stop to cast hammer, but cast speed is really fast thanks to the new 1h flail and stutter stepping with Sader's using Hammer is much easier than doing it with ranged classes. You don't really need to kite with the Sader so you just hold force move and mash the hammer key. That is all the stutter stepping needed. Pretty easy to play so I wouldn't dismiss them outright. You don't need a single bit of attack speed on gear with the build (not that it hurts but other dps stats are just as good if not better) so keeping them all at the same speed should be okay.

I will give you the fact that Barbs, Condem and Tempest Rush are much smoother, but out of those three only the Barb is competitve now since TR and Condemn don't really have the boosts that Hammerdin and WW Barbs have with sets currently.
