Savage Strike is the only reason I even consider playing 1H. With a chance of taking off the head of my enemy, that just begged me to perk up. 
As for the game being difficult, actually, I didn't find this a problem. With 1H, you can easily dance around your enemies, and side step attacks. A greater range of flexibility as well because of this.
However, if you build up your stats too quickly, 1H becomes boring, even with the decaps. Balance your game well, and 1H can stay a challenge.
Dragons take a bit longer to take down, so be aware some will fly away since you didn't down them fast enough. If you're looking to loot bones for armor, this may prove a challenge.
Other than that, you should have a pretty fun game. 
PS: this skill is really fun in the DB quests.
