You say this like PMing someone while cloaked as an engagement notice is a bad thing...
It isn't.
Also: at any given time, I can have upwards of 3 PM chains going with people I'm not even near, or planning on interacting with. These are typically OORP buddes that need to know stuff in game, or I'm generally just talking to. Things like these need to be taken into consideration before just flippantly asking for PMs while cloaked to be disabled.
[ sci·am·ach ]
/sīˈamək/
