beserker or menace?

I was playing as arlinn kord using village messenger as
my werewolf which tranformed to 5/5 menace. my
opponent played one of those angels (I’ve forgotten
which) and gave it keen eyes to make an 8/10 creature
with vigilant, flying amongst other abilities. I play
murderers axe(+2/+2) uncaged fury(+1/+1) and arlinns
1st ability (+3/+3) to make my werewolf 11/11 and
double strike, beserker. with the intention to kill it. what
happened next was 11x2 damage to my opponent.
versus other creatures beserker takes presidence and the
creature is killed. what should happen? is this a bug?

It seems fine to me.
Your had a creature with Menace and Berserker. The opponent had a creature with Flying and Vigilance.
Your (non-flying) Berserker creature could not attack the Flying creature.
Your creature with Menace could not be blocked by (one) creature with Vigilance.

thanks, I didn’t think of it like that.

kept on thinking my berserker would run head long
into the vigilance.
