In my opinion....
Grenades thrown at short range should have higher damage. The further away you are the less accurate the grenades become. Something in the type of, a grenade on its own thrown from mara church towards the hardline should go on the road or hit the vendor or whatnot.
They should be part of the Operative tree, spanning from Gunman the same as Sniper.
The tree could go like this
.............................................Grenadier
.....................................____/.........\_________
..................................../ ....................................\
.................Throw Grenade.............................Launch Grenade

Fire In the Hole Unholy Accuracy
You need grenadier loaded as your standard top of a tree ability giving resistances buffs etc.
Throw grenade Focuses on Area damage and not on accuracy, It has a Medium-Large Re use timer. Its AOE Should effect all PvP players in that area, friend and foe (Should discourage some random launching into a PvP battle if your friendlies are in there on foot).
Fire in the Hole causes larger still AoE damage, but is even less accurate than throw grenade. It has an even larger Re-Use timer. They dont have to be aimed at specific players, more areas.
Grenades are done on Useable items that must be either looted or coded.
Launch Grenade requires you to have a Grenade Launcher as well as grenades in your inventory. Launch grenade focuses on accuracy at the expense of AOE and some Damage. This must be aimed at a specific Player and damages both parties in interlock but not other people close to and shooting.
Unholy accuracy Is a highly accurate form of Launch Grenade. It has a slight damage increase and no AOE of the general area still. The damage increase should be small, not as much as Throw grenade to Fire in the Hole. Its main ability is being able to launch the grenade at a greater distance.
All grenade activites should have large re use timers, to stop spamming. Both sides should work on a re use timer. For instance if you used throw grenade with a re use timer of 40 seconds you couldnt use Launch grenade or Fire in the hole or Unholy accuracy for that 40 seconds.
When using the grenade launcher You are rooted and pacified for a set amount of time after using it, to allow for it to cool down enough to be placed back in your inventory. The longer the range you are launching the longer the effect lasts. Stopping someone hyperjumping down, launching a grenade then buggering off again.
When using a regular grenade you are pacified for a much shorter period of time and are not rooted.
Grenade defense should be counted within thrown Items.
The next bit is a bit im not too sure of. If you have a better idea for it just say.
Hackers should be able to locate rooted grenade launchers or otherwise with a "Sonar Ping" like ability. You would use the ability, a system message would say "Hostile Grenadier located" and you would get a waypoint, this waypoint would last a set amount of time until the ability deactivates and there would be a reuse timer on a second attempt at location.
Hopefully some of the things outlined here should address balancing issues and spamming issues. If you want to add/change/flame any of this feel free.
