the worst unit ever

kinda hard to argue when NOD Arty takes the cake by a wide margin =p but if I was to argue for the 2nd worst unit, it would be tick tanks. They cost 20 tib more than their scorpion bretheren, almost always lose half of it before getting into position, and when they do get there there is more 2 ranged units or flying or infantry counters that can remove it at a decent pace and for cheaper than the tick itself then there is units that the tick threatens. In almost every case, a regular scorpion tank would have been better than a tick. It takes a REALLY strong commander to make it have any value (or a very poor opponent.)
