Any friends tried the HR for the standard arena? How many wins do you gain?

How can that be an average if it requires a zoolock deck. The idea of arena is that every deck is different and usually a lower power level than constructed.

As for OP's question, by my experience i'd say around 0-2 wins per run with really good decks getting anywhere from 3 to 7 wins. I don't recommend using arena with bot, its far more efficient just running casual to gold farm.

thanks everybody for your kindly replies. I have tested its arena ability for 20 runs recently and the average wins is 1.4.

AFAIK, the bot is not good at choosing cards. I was watching at it when it chose cards, and I think it can be improved by referring some other websites. And since it can't predict spells and also doesn't like to choose spells, it is very 'greedy' when playing arena, though I know it is hard to implement in software. However, the bot is still not bad at minions change and deciding attack minions or the face.
