So in Gambit prime the armor for sentries suggests two jobs. Knock down blockers and counter Invaders. It is worth noting that these two jobs conflict with each other basically every invasion since it is very likely you are getting a blocker dump and an invasion at the same time, so you have to choose - either let motes drain or let an invader chase down your guys with motes. Either way it is "Gj sentry..." But that isn't even my main point. My point is how bad sentries are at countering Invaders. The blocker focused perks are underwhelming but at least it adds some value and taking out blockers is possible. The single anti-invader perk (marking) is a fine start, but it changes very little little in a sentry vs invader fight. The invader just has too many advantages. I think Invaders should be concerned about going up against a sentry and feel like they might be better off if they avoid the sentry, which right now is laughable. Unless I have help, right now as a sentry my standard invader process is: - find them - mark them - get killed by them in the process - hope my team can use the mark to avoid them or finish the job. That is not a fun role. So here are a few random examples of perk ideas for making sentries more capable at countering Invaders while still leaving Invaders powerful: - sentry can intermittently see invader tag or location on radar - sentry tag intermittently disappears from invader hud - sentry has a large slowing Aura as invader gets closer to them - sentry gets a shield/shield Aura on invasion - damage from sentry drains heavy ammo - sentry gets super energy on invasion - on death sentry spawns taken dogs that chase invader - sentry grenades gain that time slows down/sticky debuff And I'm sure there are plenty more. You get the idea. Right now sentry is just another kill to invaders. Make it so invaders have a reason to be concerned about sentries.
