TTK is not only perfect, it's sheer utter genius because...
1. it makes combat more exciting to experience and spectate.. because people don't die in 2 seconds. watch shroud spray two clips into someone and tell me that's not the best looking, best feeling eye-candy in a battle royale.
2. it makes the game more forgiving to learn for new/bad players, because they don't have to spend 15 minutes of looting to get only 3-8 seconds of combat (hello PUBG). THey are still going to die, but at least they can usually unload a clip or two before it happens, which is good practice.
3. it encourages teamplay... because a great way to reduce TTK is to get 3 guns on an enemy instead of one
4. it raises the skillcap... if you are complaining about TTK because you want to run around and 1v3 teams, you just need to get better.. obviously it's not a problem for pro streamers.... having a higher skillcap gives the game more longevity and depth
5. The long TTK and the banner rez mechanic decreases RNG, which is a good thing... pro streamers are winning nearly *every* pubg game they play... which is how it should be. Because they don't get downed by a random dude that just got 2 lucky bullets into them in a 3rd party. This will set the game up for team ranked queues and esports.. which will both be awesome.
If you want lower TTK, go play PUBG or Fortnite.. We're happy with the long TTK here. THis game is friggin awesome.
