i don't think it's likely that you'll see wood elves in howdahs on giant animals any time soon, as we could just climb onto treemen and use them as a walking ballistic platform. ;p
i have to say that, having watched that video that games workshop put up concerning how they generally design armies to have either big monsters or a lot of guns, i'm much more interested in having some big monsters. maybe we could have our teeman throw rocks or something. i'd also like some war beasts (spirit animals would be cool) or spite swarms or something that isn't super expensive but still thematic, for tying up units and diverting them, which is supposed to be a theme of our army. we're not really a stand up and fight sort, and i think that this play-style can still be supported, even in a game that's all about the crush of melee combat.
i'd really like to see a new sculpt for our dragon, i'd like one that's not out of an 80's cartoon. i'd like it's breath weapon to stand a chance of hurting anyone, also.
i'd like eternal guard to not be ridiculous expensive for spearmen, i'd like to not pay a premium for fear on most of my models, and i'd like wardancers to perhaps not cost so much if they are there to strike hard and then die.
i'd like to see our lords and nobles be able to shoot as many shots from their bows as they have attacks on their profile, because str3 arrows are not exactly the most potent force on the field these days. ;p if we could perhaps have them shoot at str4 in close range like their glade guard brethren that would be even more awesome.
there are a lot of small things i'd like to change, but i can understand the not-really-a-ward-save on forest spirits thing (from a fluff standpoint, certainly). however, if our units are going to be costly that's going to need to be a real ward to reflect the cost of our units. i'd also go so far as to say that we really need either ranked units or a special rule that allows us to otherwise deal with steadfastness. i'm leaning towards the latter because i think it fits the idea of the wood elves picking off army blocks before crushing them, but unless that can be made to play out on the table the former is a better overall gameplay solution.
either way, it seems like
GW is really working hard to get army books out expediently, so hopefully we won't be waiting that long for some rad new rules. i just hope they keep waywatchers awesome, i just bought a bunch more.
