So, i often see thoughts about citadel spam - yes, i think it bad mechanic, which break down game.
What fixed it? i think, it realy easy.
- no reinforcement (RF) on medium low power (LP) citadel - [astrahus / raitaru / athanor]
- only one RF on medium citadel - as jump gate / cyno beacon / cyno jammer now.
- ADD “armor reinforcement service module” - for medium citadels. It add armor RF and citadel has defence mechanic as now. This module REQURE another worked service module (clone station/manufacturing plant/drilling, etc) for armor RF and consumes fuel blocks. If it fitted without another services module - see point 2.
- Citadel can be anchored only on object orbit in space - only ONE - on moon / planet / gate / sun / asteroid belt. Yes, i know about convenience, when all production cluster (athanors/raitarus, forti/azbel/tatara, sotiyo) on a grid, i dont know, how to keep it and limit citadel in system, maybe it bad mechanic too (or you offer better variant).
- Increase limit on incoming damage (on M, L and XL structures) - at least x2.
- L and XL structures, if for a long time in LP (for example - 1 year) forfeit hull RF and can be killed without any RF.
And i hope, CCP make realy open space (such as recent bug with anomalies in billions au), when we can anchor chitadel not in system (but on some object, ccpls, do it)
