I am not in PME yet so it does not affect me yet, but this is definetelly a bug.
MG team has a range of 10 (7 in x1.5 map) when it attacks normally but
a range of 15 (10 in x1.5 map) when it retaliates.
It's description says: it retaliates always, so either it can retaliate within its normal range 10 (7 in x1.5 map) or it can retaliate within an infinite range (no matter how far you attack it, it will retaliate, even from the other side of the field), but retaliating within a specific range diferent than its normal range is a bug.
Maybe not a very importand one but still a bug
