when the bear die, the hero die too

If the other player is good as well, i think intelligent hero can kill the hero easily, ignoring the bear...
It's expensive to buy stuff to both the hero and the bear, the opponent can get a lot better items that you if you want to equip both the bear and the hero (say 2pt, one for hero, one for bear, while enemy can have one pt and something else).

On top of that, there are a lot of way to counter the bear, like disable the bear then focus on the hero... or for hero like lich would be happy to fight you and the bear together and so on....

i think the -apom mode is more suitable for 1vs1 mode..
because you only need to focus on 1 lane..
you don't need to worry about the other lane..=)
