It is a very expensive unit. Originally I thought it is a very strong unit. But after few battles, I find out it is somewhat low dpm. Now I am curious. When should I build this unit? It is counted by Artemis due to the long range of the Artemis. It also does less damage than multiple SXX with the same price. Thus, I think it is designed to counter the Avenger. But I quite doubt this. Its price is about 47 times of the Avenger, but I don't think it can really defeat 40+ Avenger.
