How would it be ludicrous, your 4500 attack would mean nothing now. You get 20 % att , the same amount of fights u would do in space age with 4500+ attack is the same amount of fights u would do in Iron age. If u are only allowed to use troops from iron
I don't think you realize how big of a difference 4,500% attack boost would make in Iron Age. Particularly if you're retaining everything from your progress in Titan.
I know prior to the most recent changes in Guild Battlegrounds, there was a Iron Age player that posted a screenshot of using Turturrets to exceed the attrition cap in Iron Age. I forget what boost they had, but it would of been a fraction of that attack stat. Iron Age doesn't get many Expansions to work with and won't have any of the boosts Titan has
If everyone could easily and reliably take units from the Space Ages down to Iron Age.... those are going to greatly outperform Turturrets due to the x2 Keen Eye boost
I'm not against the concept of restarting. However, it would need some restrictions in place to make it viable in a multiplayer setting. There's no way to separate a Space > Iron player in Guild Battlegrounds from the rest of the playerbase. There wouldn't be enough players restarting to separate them. You also wouldn't be able to remove Space > Lower player from the neighborhoods without finding an additional 80 x 20 (1,600) players restarting on each world to do it with. So the only way to have a restarting mechanic is if those who restart are mixed in with those doing it for the first time.
You would need it balanced in a way that restarting isn't going to create too great of a power discrepency, but also retains enough advantage to make it entertaining for the player that's restarting
I agree with ebe, it'd make more sense to travel back and forth between the Space Ages than it would to choose any Age
