1. warp time to travel to target,
Anyway if U could record this sequence on 2 gold brutes, that wld be awesome even if it takes 7 sec
2. One claymore shot is still better than one melee, but slows u closing in. Can U hide claymore reload with melee ?
Sorry man, I can't play the game these days, let alone record it XD
Anyway, I don't understand what the problem is. Warp -> claymore shot with warp ammo IV -> cluster grenades kills a gold brute outright without headshots. So clearly doing that two times plus one more claymore shot is going to do more damage than their health combined, that was my reasoning.
Now, if you're questioning whether one of that combo can kill a gold brute without a headshot well, I believe Feneckus has one of that recorded and I could be able to find it and link it. I can assure you it is like that, anyway.
If, instead, you're questioning whether you'd be able to pull that off in 5 secs, well... Assuming the target is very close, the time needed should be roughly the one of 2 claymore reload (hidden an canceled) + a warp and a cluster animation. Which should be around 4 s + 0.5 + 0.5? Something like that...
About the GI, I'm not sure if you can hide the claymore reload into the melee, but I'm pretty sure it can't be done reliably, cause it's the same for every other melee. So you might be better off with one shot, but certainly not with 2. Melee DPS is stupidly high., much higher than a claymore's.
