the 1st time i played it the game just randomly ended and said "Player 13 has won" it seemed to just end for no reason at all.
A couple of times i'd be fighting creeps and use my Blitz Strike on them and it didn't hurt them at all. One way I could recreate this every single time is if i didn't have vision of a creep camp and used blitz strike on it, my hero teleports over to them and i can see them and they attack me and then i teleport back to my starting point and then walk over to them i can see they took 0 damage but i took damage from being teleported over there and got attacked. It probably has something to do with not having vision, but if my hero gets teleported over there and i can see them then they should take damage or i shouldn't even be able to target the area. *but* this is not the only instance where blitz strike wasn't doing damage. sometimes i had full vision of them and used it and it did no damage. It seemed random when it would work and when it wouldnt work if i did have vision of the creeps when i cast it. when i did not have vision of the creeps when i cast it 100% of the time it did no damage.
also... the flags. We played a full game with -50trio and I was the only person on my team that could cap the flag, and since the flags aren't droppable and teammates cannot attack eachother, We had to wait untill someone killed my allies with flags so they could get normal movement speed again.
Another thing was with the random teleporting to the brawl area, i got stuck on a little 1x1 piece of the ledge of a cliff and my hero had no sort of blink, i didn't have one of those teleport items, and team mates can't kill me, so I had to just sit there and wait for someone on the other team to kill me.
