Disabling Shot and one handers

One of the first things I discussed with my newb friend was which melee weapon would he be using. He said he wanted to use 1h swords plus shield as his main weapon. Unfortunately I had to tell him that all the one hander are severely underpowered partly because of Disabling Shot. First of all, there's some balance to be done because noone uses mounted combat anymore and people uses the 1 hander so they can block with the shield when caught in a bubble. I haven't done any tests so I don't exactly know how underpowered it really is but the fact that anyone can disable you ability to block at any time, even if you are not blocking at that precise moment, is very bad for weapon balance. Also, even if Av has been ninja tweaking the weapons balance if we players don't know that something is viable again, we won't use it and the game will loose variety. On the other side, I'm a knive user, both in PvE and PvP, and I use this weapon because I like it so Anthas might just do the same thing. What's your opinion on this subject? What would you recommend Anthas to do?
