Isn't Blizzard cracking down on trainers? I know if you use cheats, you disable achievements. However wasn't Blizzard closing down accounts if they caught you using something like this? (Even for Single Player)
for the Nth time, yes. You'll get banned. People who are using the trainer are likely disconnecting themselves from the internet after game loads. Once you do so, you can enjoy cheating the game but you don't get achievements. Blizz was banning people on the principle fact that it didn't want people getting achievements by cheating.
