I played a demo game of both warmachine and hordes and I think I am going to pick Legion of Everblight. I have to have aesthetically pleasing models to play but want to be somewhat competitive. Take the centurions from SM, they are very good however if I played SM I would never play them because they look dumb imo. But I like just about every model/unit from LoE

So, now to some questions:
1) I have heard that Legion of Everblight is a glass canon army. Is this a difficult force to play for a new player?
2) What is the typical playstyle of the Legion, or general strategy? I've heard that lots of people run assassin armies that just try to kill the enemy caster instead of getting objectives (the group Iam going to play with typically plays annihilation over scenario anyway)
3) What drew me to the Legion was its fantastic warbeasts (reminds me of nids) and while I am not opposed to using infantry or solos, I think I would like to run a beast heavy/oriented force. Is this feasible for Legion why or why not?
4) Would you say that Legion is more of a ranged or melee oriented army, or a mix of both?
I have 2 $50 amazon gift cards that I plan on spending for this hobby, atleast to get started, but I don't have a lot of extra money to spend (When I say that, I mean I really shouldn't be getting into an expensive hobby to begin with XD) So I want to be very smart with what models I purchase. I am hesitant to pick up the battle box because I have heard from the one legion player that it is good, while the other says she doesn't use any units from the battlebox in her actual army. The group I am joining tends to play pretty casual but they also go to another hobby store whose players are a bit more competitive and run lists you might see in tournaments. I'm not in the mindset of "buy models x y and z to have a competitive force" I understand it is also how you play, but again, without toomuch spare cash I can't really afford to be buying units to replace other ones if that makes sense.
If there are any other suggestions you could give me that would help out I would really appreciate it. Thanks for taking the time to read this and help a new player out:)
Really excited to get started.
p.s. It was very hard for me to pick a faction! First glance I picked Menoth because in RPGs I tend to roleplay as templar/paladin characters. Then it was like "oooh persian samurai? I want Skor- oooh! That guy is riding a goat! I want to play Circ- ooohh..." I am by nature a very indecisive person...I think. Am I? I don't know...
