I think Gorges should push E on a Marine res node. A bile Det pack should spawn, take X amount of time to be placed, hum time should be equal to the time it takes a elec node to zap the gorge to death with out third hive or carapace/regen. In which case if its a elec node it should require ether two gorges *one healing or DC's / third hive. in which case if the gorge gets interupted, killed or has to stop and say heal a fello alien his bile det pack timer resets and he has to start palcement all over again. Once placed the muccus bomb begins fireing off bile bomb exsplsions, which raipidly kill the res node, the time it takes to kill a node should be no faster than a non adrenalined none mc'ed gorge bile bombing, at which points the only way for rines to remove said device is via a incindary device like a gl grenade or a hand grenade exsplosion with in the radius, like takeing out web, prahaps welder also.
The momment the gorge first clicks E, the Marines are informed node under attack until ether its intrupted or the node is taken out. Also being a sort of DoT effect, rines will be required to keep their nades handy for res node cleansing even if the gorge is their or isnt. The bile exsplsion on the node could also effect rine armor if they are silly enough to go near it note the weld removeal.
The whole effect over time is. If your rine team Is silly enough, not fast enough, not paying attention and so on. Why shouldnt a gorge beable to take out your res node, with out fear of being zaped to death, or with out haveing the feeling of watching paint dry.
