My league has the following teams:
Orcs x 2
Chaos Dwarfs
Ogres
Norse
Lizardmen x 2
Goblins
Humans
Vampires
Chaos
There's a few experienced players, but most are new, and I'm by far the most experienced coach in the league.
We're using LRB5b rules, but there's a bit of a quirk with how the rules work. Each week you have a scheduled match which is a normal game (will add in a random 50k special play card for both players soon I believe), and you can play one other friendly match against anyone. In the friendlies, nobody can get hurt worse than MNG, your FF doesn't change, and you can earn max 20k.
So game 1 was vs CD with a bit of a bench (2 bulls, 4 blockers, 7 hobgobs). My roster is the 4 warrior, 7 beastman, 3 reroll version. I managed a lucky 1-0 win after bad dice in the first half (2 turns of failed pickups and 3 players KO'd to none of his). Second half he misplayed his offence which let me recover the ball.
The team was a little more solid than the LRB4 version, with a strong line which wasn't possible, but the main weaknesses are still there. You roll both downs just as much and ballhandling is still tough. The extra warriors were helpful in tying up players more than anything, but they're not much of an overpowering advantage.
Second game was a friendly against vamps which was a 2-2 tie with me actually being outbashed (1 MNG for me, nothing done to him). Sometimes AV7 acts like AV10.

Next I had a scheduled match against the vamps in which I got hot dice and won 3-0. The extra arms beastman was really useful, allowing me to take advantage of a blitz with a ball scattered to the line (catch on a 3+ rather than 2+) and in general just to allow me a little more flexibility in playing the ball, like running a short passing attempt when the rerolls were all gone. That's actually something to consider....passing isn't chaos' forte, but it's not something to be afraid of trying depending on field position. During the game, I skilled a third warrior and have block across the line, and I bought my 12th player (a beastman). So my skills aren't that interesting as of yet.
My plan is to buy a minotaur, which I'll likely get tents on ASAP considering how many low strength teams there are, and to just get lots of block on the team. If the league was a little more balanced (aka....not over half of the teams with S2 dodge players), I might be tempted to take some early claw and frenzy, but those will wait for now.
I'll be updating this with my thoughts on the team, and on the league developments as I gain experience.
