I've gotten the impression that the main problem with stockrooms is that they allow people to do as the yw ish (teaming, jumping, etc.) while not dealing with the consequence. An example, though I consider Hekate a fine opponent, the last two times I've come into Thakria, she's been sitting in a stockroom.
I've attacked her friends, and the she has moved one location outside of the stockroom and sent in a blood demon to my location. Thus, she is not attacking from the location, but were I to try and get to her, she could instantly run into her stockroom, and there would be no repercussions for her actions.
I feel as though the ability to enter a stockroom while not either DP or PW should be slowed by a permission process (as no person should be able to go out, fight, then rush instantlty to complete safety) or by the ability to traverse to people in stockrooms.
The stopping of people doing comms will not stop the main problem, which is people using stockrooms as saferooms from combat.
You say that stockrooms should not be for hiding. If people are still instantly able to rush back into a stockroom, how will this stop the issue of people hiding?
