Dealing with the past:
1) All terraforming charges ever bought would be respawned to the character that bought them
2) All gamma structures linked to a corp would be server deconned and placed in the corp hanger of said corp
3) All corp assets would be placed in the same hanger
4)all personal assets would be placed in peoples alpha hanger
The future:
1) Maintain current terraform mechanics but:
2) Limit the number of structures per base
3) make terraforming and contruction only able to be done 3km from a terminal
4) make bases be placed 5km from each other and from the teleports
5) Limit the number of bases to 3 per island
This would force people to create small contained bases but still have some of the awesome beautiful terraforming you see around the game now. Changing terraforming inh the way you describe will make gamma bland and miss out on some really cool design.
Proverbs 23:20-21 warns us, “Do not join those who drink too much wine or gorge themselves on meat, for drunkards and gluttons become poor, and drowsiness clothes them in rags."
