yep, diffusal dagger the tested and proven build would have been a lot better.
he could have had massive kill threat early on a bunch of og heroes.

ursa battle fury needs the other core to make space, wyvern is not that hero.

wyvern core needs other core to front so wyvern can dish mayhem from the backlines, battle fury ursa is not that hero

ursa should have gone the diffusal dagger route, then bkb shard later. COULD HAVE gotten in the face of ta and disruptor early on, and potentially snowball out of control. that battle fury just messed up their timings and they didn't have the heroes to make the space for the "battle fury payout", ended up as a useless 4k gold item.

just one item choice, insane impact. undisputable ez game. not the game 5 anybody wanted to see, that's for sure. disappointing to say the least.
