if you want structure in high sec, then be prepared to defend it. You can’t set up your own structure and be competitive against other while having invulnerable shield protected your structure
with change on wardec, you can opt out by not have a structure in space (only high sec pvp you will face is ganking at this point) If You want structure, See top of my post^
Speaking of WoW, Blizzard makes a big change to encourage more PvP, so I guess Developer see PvP as a good thing for MMO.
