I've been running a 1000 point all mounted Rohan army recently to see if I could make it work (clue: it's just as tricky as you'd think) and have been having a fair bit of success. I've been playing for the fun of it more than anything as the army just looks AWESOME on the table but I've certainly had more success with it than you might imagine and obviously it maximises the benefits of 100% bow quota.
It's hero heavy (7 I think) and packs in about 35 models all told giving me somewhere in the region of 28 shots per turn. My opponents have said that it's actually very intimidating to play against as you can sit back from your opponent and wait for them to come to you, softening them up with bow fire and then delivering a devastating cavalry charge to the shattered remnants of his army.
In theory.
The reality is that the S2 bows need 6+ to wound far too often, D5 is just far too prevalent across the board. This means that whilst I'm rolling lots of dice, the casualties are often few and far between.
The second thing is the -1 to hit if you move. This is hideous. It's my least favourite of the new rules and it has a massive impact. In SBG you are constantly manoeuvring for the best position which means that after the first few turns, most of your riders will have moved, further reducing their chances of doing damage. I still haven't got over the psychological effect of rolling 4 dice and seeing a 3, a 5 and two 4s come up and thinking "I would've got 3 hits in November"
The 8" throwing spears bonus is nice though, particularly when combined with their S3.
Ultimately, the 100% bows rule helps but the movement modifier and S2 means your can't by any means rely on your archery.
I still believe the all mounted Rohan army works though, it's also oodles of fun to play with so I will struggle on!
