Sure, they should just retcon and remove anything creative or beneficial in the game. Anything more than the bare necessities needed to survive in PvP should go on the chopping block. To hell with people that want to play cooperatively, to hell with PvE and their public works.
EDIT: Also, just because you visit stuff regularly is no guarantee that things won’t just poof for no reason, even on a PvE server. Part of the reason myself and other use this technique is because the decay system is so unreliable. I had a whole T3 base at Sepermeru poof after only 3 days a few months back FOR NO REASON:
Another of my friends had the same happen with one of theirs in a different area too.
And just today, the replacement maproom I built at Seper (which is linked to my other bases) just decided to decay in spite of the fact that my clanmate and I visited it just yesterday.
Gonna wait until tomorrow morning’s rule-changes are thru tearing up the server before I go making another maproom… assuming anything is left standing. And yes: for the record I’m incredibly upset right now.
