I used to always defend the inks stun, but not anymore, you know why? not because people are using the ink on me always and getting cheap kills, it's because after thinking long and hard i believe that the ink isn't and "ink" grenade, it's a "stun" grenade.
I believe increasing the inks radius by x3 is good enough, by my logic. Obviously the stun needs removing, in place a higher damage output for the ink should be added so if a player was to stand in the ink radius they would go in DBNO in around 2 seconds, maybe 1.5? just to make it lethal.
Tournaments are removing inks just because they think it's "op" and the pros will abuse this grenade that spawns near spawns on certain maps.
Just think of it like this, if a team is camping like idiots and you get this gears 2 ink and throw it at the area, they will all have to move or die in an actived lancer time. Then when they move, assuming they have taken some damage, you can push them.
I can easily avoid getting killed by inks, simply because if someone is holding it, i will be aware and ready to bounce, so if they don't change it i am not going to beat myself up about it. But the change will give back the inks personnel character and use, it will set it apart all the other grenades.
Frag Grenade: Timer, then will explode, produces high damage.
Incendiary Grenade: Instant kill upon impact or gradual damage if enemy is standing on the fire.
Smoke: Blurs enemy vision, good for flanking, has a little stun but you can move, the stun is great for this smoke, gives it another use for smokes apart from the grey smoke it creates.
Ink (gears 2): Big radius upon impact, stays around for a long time, good for killing campers and flushing them out, no stun.
Ink (gears 3): Stun, player cannot move while stunned for like 2 seconds, little ink damage, if directly hits enemy then they are dbno (like the incendiary in a way, because once you go into dbno you die super fast, it was a waste of time to go into dbno but obviously the incendiary is insta kill upon impact), cannot flush out campers, created for 1v1 combat (much like the hammerburst with it's small magazine)
The gears 2 ink sounds unique and better, the solution isn't to remove the stun because if they remove the stun from the regular gears 3 ink then we will have another useless weapon/pickup. It will do nothing and MIGHT assist like the digger does on unaware enemies.
The REAL solution is to remove stun, increase ink radius and to make the ink have a high damage output while the enemy is in the ink.
