I’ve seen it quite often (well, almost always) that gate campers use local chat as an indication of a ship jumping in, which allows them to effectively trap it while it’s gate-cloaked before it’s pilot can take any action. This is either by dropping an interdiction probe (which normally takes a while to expand) or simply knowing that it will de-cloak within 60 seconds and instantly locking it (happens because the window is so small and well-defined).
I think these possibilites kinda take away from the purpose of the system change protection and makes ships with low but >2 second align time pretty meaningless in these kinds of situations (extends to non-interceptors for nullsec). It also allows gate camping to be a pretty passive activity with no real drawback when treating it as such.
As an improvement, I would like the gate protection to extend a bit further. That is making the player jumping in not visible in local chat until he drops the gate cloak, speaks in local or uses D-scan. This would effectively mean that campers can tackle a ship while it’s aligning but cloudn’t prepare for it unless they have more intel (having align time minus 2 seconds to react).
I think this should bring gate camping towards being a thing done for a specific purpose for a short period of time rather than being a kill-hoarding activity.
