The Heavy attack oog inside minions doesn't work like it did before. If you do this to kill the minions, one of them bumps into you, interrupting the 2nd (more effective) heavy. i hate this! change it now!
If you move bit between the minions you can get x10 with 1 heavy. But you are probably right that it was better before. It is a really stupid bug and it is a100% repteatable bug aswell. I dont understand why it isnt fixed.
