Not exactly hard beating your average destroyer in 1 v 1 there buddy you can jump around and half their CC's that aren't pulls will miss you they don't have an air combo and have a measly 6 second moment to burst you to death. if you lose 1v1 to a dest you were 100% out played.
as far as 6v6 goes it sounds like you know what to do, so why the hell aren't you communicating with your team you got time before the match to say "hey guys if the destroyer is spinning don't hit him." your logic is "nerf destroyer because my team is bad" thats completely asinine and thats why im focusing on destroyer. there are 5-6 other classes who do WAY too much or are just out right untouchable.
FM- 20% piercing on orbs has can dash up to 50m away virtually untouchable because of their MASSIVE damage and defensive capabilities
SIN- Taxi and stealth cheese beluga , plenty of CC's to instantly kill you or set you up to be murdered by the rest of the team hard to target because of stealth and flash
BM - Air combo's and you're dead , nearly untouchable
BD - the same as above but can grab you anytime they feel like it
WARDEN - nearly invincible with basically 2 life bars nearly impossible to CC's also has massive pierce boost for 6 seconds to basically ohko you if you're not paying attention. and soul burns the party with more HP
KFM - +legacy peridot resist cc for 3 seconds when upon evasion and they can't be CC'd Q/E agiity boost evade everything some more and then prepare to get killed by Tab + V+4 instantly and they counter everything
SF- basically can't be touched either
SUM - instant summon massive dpsing cat that basically can't die and can stealth and flash bomb
Archer- zippy dip endlessly launch and pop tab ohko lol stealth
which one of these are you ?
here's another thing. Shadow destroyers have a pvp debuff called scar, this lowers your pvp defense by 1000 upto 10 times but each destroyer can only apply 5, these scars come form them hitting you with red spin or you hitting them while they have their shield up. this defense loss combined with them stunning you with 5 hits and their team firing at your team is why you guys are getting your asses handed do you imagine a FM with their 20% pierce powered up by BB or SB hitting your team all inflicted with -5000 defense because you all decided to get hit by the destroyer or all decided to attack their shield you're going to die.
90% of the time the destroyer is stuck defending the post so how about just avoiding them or tell your team to leave them alone
Deal with redspin dest -
•spread out, root if you can (WL SUM SF), ranged focus them especially FM's
•dont hit their shield
work with your team ffs
