New Air Unit: the Zeppelin

Hi, as i first started to play this game i thought the balloon was a zeppelin and wondered, why it has to embarque when going naval. as i was informed by Dr.Schnaps i thought it was strange that there was no zeppelin in this game, where they had their big time in this war. It braught me to the following: 1. Balloon: buildable with workshop 2 and air field.to sew an balloon you don't need a factory in my eyes. rest same as atm 2. zeppelin: buildable with factory 1 and airfield, costs: 1000 iron, 3000 wood, 4000 gas, 20000 money. stats: ground at 1,5 def 1,5, air at 1 def 1, buildings ar 2, def 2 HP 2 something about that... what do you think? best, grot PS: i still dont see what im typing
