I find myself the ghillie suit is unpractical cause it lacks the ability to carry helmet, it makes you die from a poltergeist/burer/controller's aura, like always and usually within seconds. The seva suit should have a better stamina built for a recon. Also ergonom+50 should become something else like +1/2 or whatever is most logical, now ergonom

practik (edit)
Yes, ghillie suit having very small protections parametres, but it's means you should use long distance tactics. i succesfuly figthing with these monsters with ghillie - i just playing from long distance. For recon - how i said, it's need to seva at Nimble, can be having price some about 120 000 but it's making choice to player - intensive collecting money now or waiting for appearing suit at traders, at the same time using some worse suit.
BTW - about Ghillie - it's should be good to ability to use helmets or increase some parametres like radiation protection. I think adding or changing upgrade scheme will be good - opportuninty to upgrade psi protection, for example, set some addition layers. How we can see - ghillie covering head too. But - Ghillie is don't battle suit - this 1st reason that this don't need to do. This can break balance. 2st reason - the sense and purpose using ghillie - for masking is dissapearing. If ghillie will have some big upgrades or ability to use helmets - it's will make ghillie like usually suit and will break balance. And if good to think - let ghillie rest how it was. But seva it's need to add to Nimble for recon, it's will have smaller volume of working and will be faster and logical. This fact that ghillie have some small parametres make a choice for player - you can playing like sniper and use masking or you will don't have a masking and will have good protection, but you will not real sniper, you just like assaulter.
That reason i want to ask -don't change something with gillie - this will kill interesting and sense of using it.

Easiest is the Ghillie can be worn with helmet i.m.v. There are enough places you are forced to be nearer to burers for example in jupiter. If a sniper was all long range he didn't need a shotgun perk to begin with. Just using psy drugs or weed is not enough when handling more then 1 burer.

practik (edit)
I played all time of mod with ghillie. I used Seva at small situatuions - in underground, collecting artifacts and in evacuation quest. So, i can say it's possible to play in ghillie. All what you need - remember what you playing as sniper and use his tactics. In jupiter i killed burers from entering at depot on second floor. Just sit and shoot - it's all what needed. I using shotgun only in unexpected close attacks. Sometimes i going only with sniper rifle and knife - i don't had any problems - it's all depending of your skill and accuracy. I went in Jupiter plant in ghillie - im used some creativity and enticed snorks, killed them and after this i m easy went and killed poltergeist and controllers. Before going somethere - i using scope to check area and after this - i going ahead. This let you avoid unexpected attacks of many enemies including psy. I think many players having problems because they don't understanding all sense of class diversity. They trying to play like in vanilla - this causes issues. Different classes - different tactics, ways and equipments. BTW, don't forget using some modules and additional weapons like mines - you will see how playing can be easy. Just use you brain and cunning - it's interesting and fascinatingly
How i said, sense of classes will lost if change something.
So you should remember that each suit having own appointment. Don't try closed fighting and going in anomaly in Ghillie and use correspond equimpent for any purposes.
