So, the bot just used 2 holy light on a 1/1 frozen minion (those you summon with paladin ability) - he was even with full health...)
Also, while playing Shaman, i have problems with Ancestral Healing, it tries to cast it while i have only 1 minion with full health, and just keep selecting and canceling...
With Warrior, it used Heroic Strike, and just ended turn without attacking (opponent had a 2/3 non-taunt only)
