Disagreed, meds negate all the damage you did, but all the other things you mentioned don't negate, just add to the battle.
They mitigate some of the damage that was done, Let's say you got instafalled, but they failed to kill you because they had to reload and you think "Wow. Instafall, That's so lame!"
Veteran channel is where they really matter, to be honest, and beginner. Later on, everyone has breaker 7-8 that can just 2-3 shot.
I mean really
20/20 damage mitigation = 3 sword slashes
30/30 damage mitigation = 5 sword slashes
That's really not a big deal.
Meds have a practical, but not optimal use, because you have to run off and hide, wait for the med to drop, then nom it.
In that precious 5 seconds it takes, the game could end.
I cannot tell you how many Duel Matches I've timed, and clocked my win before 30 seconds.
Then again, I cannot tell you how many times I've had meds, and been dropped before 20 seconds.
The speed of GunZ, will overtake most medders to negate all damage mitigation via healing by medical, armor repair kits....
The Vials though, are brutal. One click, and healing for 5 seconds. Whooie.
I use them during quests, very handy.
