Ok we were on about this yesterday so I thought lets read the bloody forum about it, staretd reading it this morning and it seems like the Town centre actually has a bloody attack (would help if they specified that before but they never), the town centres attack is higher than a single slinger and that is why you always lose a slinger when attacking, if you do try and attack an inactive then make sure you attack with 2 or 3 to be sure in the attack, on a side note remmeber when sending your units out their upkeep doubles lol.
