Sorry Wyand, you're off on another tangent. Yes, it's about grinding. No, it's not a crapshoot
It is a crapshoot in a way that your success much more depends on which sort of AI4 you get to play. As iancu mentioned AI4 is
faster because you often get rekt very quickly.
Of course you can optimize your deck but when you have so little option to change that optimization won't change that much.
At least for me it isn't worth the pain.
Amusingly enough cg happened to grind a ridiculous amount of diablo II (great screenshot of 49 level 90+ toons..)
Some patience. Tbh I wasn't a fan of battle.net play because of the economy (filled with ridiculously overpowered runewords - and the runes where basically found by bots and/or duped...).
Battle.net was interesting only because of special events. Nice offtopic, heh.
btw 3-6 is a terrible sample.
I know it is a small sample but looking at my cards it won't be much better playing 100 games vs ai4.
Btw my point - if it wasn't understandable - I'd like to have some fun when playing. Even if it is a hard challenge. It was fun playing AI3, having all sort
of epic wins with ragtag group of cards, but it sorta loses its thrill after a while. Percentages and optimization won't help. Not saying you shouldn't enjoy it,
was merely pointing out some stuff how to improve on the experience - but sadly we don't have a dev around.
