You need to avoid getting stunlocked by Destroyers. Mainly play hide and seek with them; #2 often to stay stealthed and only do damage when you are 100% sure it’s guaranteed damage, then back away.
This is boring/annoying as fuck but you will win by score in the end if you do this.
Destroyers with Smash and Fury spec will do over 15K damage with just Smash alone, if it lands while you’re stunned.
If they anicancel you, it’s another good 15-20K+ easily in just a few seconds.
However, if you can lure them and bait them to blow their stuns and or Fury, they can’t do this again for a while.
The highest I got as Destroyer was Blade & Soul Gold, before the patch and only Assassins that would play hide and seek and win by score would beat me. Keep in mind, I am not one of those Destroyers that has played the foreign versions for months/years. I barely had one week experience or so after I hit Plat; so someone with a lot of experience behind them, may have better suggestions.
8-1 1533 rank roughly as Des. There are quite a few players I run into that understand what I’m trying to do, but the people that don’t usually Tab-escape my first CC/LB+RB combo and then die to CC+Smash+LB/RB+CC+LB/RB+follow-up die extremely quick. Make sure you Tab-escape during the opponent’s IMPORTANT skills, and not just as soon as you can. It will make a huge difference. Especially assassin/summoner. The good ones I’ve fought have absolutely destroyed me. This is coming from a previously platinum ranked Des, so I’m not the best but I’m not awful either.
I am seeing more and more of my stealth breaking for no reason because of server lag with Blade And Soul Power leveling. I am also seeing where my TAB on launch doesn’t come out at all or it comes out and goes straight into webbing. This is me literally waiting to launch them as well after I stun them and not spammed immediate after.
