I agree with you about how it was necessary to build honeycomb/stacked bases to ward off how bomb damage was almost impossible to defend against. I even made a post about it, explaining why PVP bases required larger builds.
So ya, there’s going to be an imbalance here to a degree.
Remember when it took more bombs to take down a vault? That hasn’t been changed.
Unless you’re a serious raiding clan, the majority of PVP players do not know how to cheese/strategize everything. Like bomb spam, understanding bomb placement, making quick calculations on bombs required vs. building health.
The length of bomb placement also created such situations of naked bombing. You take what, 5 to 10 precrafted out and die and STILL you were able to get through? That should never have happened and was in many ways meta for some.
Using explosives should come with great risk as it used to be. You had to be smart, quick and be ready for anything.
It will probably take some tweaks as time goes on. Unless Funcom starts setting up no rebuild during PVP time, everyone will have to git gud, so to speak.
