The most annoying team to fight against usually consists of 4 tanks and one damage dealer

I mean, I've done my best. I've listened to the critique and built the so called anti tank items. The duskblade, the last whisper, botrk, and more. Mixed them up, tried doing other things. But it never seems to help.

For instance, my last game I played not too long ago, I was Kha'Zix. Me, the ADC Vayne, and Thresh were all trying to focus down one tank. One. Tank. She was going to town, doing the three hit combos, I was using my Q cause he was isolated, and Thresh was doing his best to CC this guy. But this Mordekaiser couldn't be killed. I get his abilities give him shields and stuff, but when you got Isolation Damage as Kha, Vayne's silver bolts, and thresh's hooks and ult all working to kill you, and all you do is just use a few abilities then get a triple kill, something's not right there.

You can't believe how shocked I was, just how unbelievable it is that Mordekaiser was able to turn around, and kill all three of us and leave with 3/4 of his HP while chatting in game to all saying, "Git gud noobs".

....

It's like, what the hell happened? How did he leave in tact with so much HP by himself and kill us three. It's Mind Boggling.

Then for the last ten minutes the rest of their team: Blitz Nautilus Vi And Lissandra just couldn't die no matter how hard we focused on one of them at a time.

It's so disheartening to watch a whole team build defensively while dealing metric tons of damage in return. I'm at the point to where if I see in the Draft Pick if the enemy team has a tanky looking team, I'm just going to give up and leave the match cause I know they are going to win. It's a fact. A team with 4 members having over 4k health, and defenses out the wazoo that you can't kill them. They mock you in chat, tell you to get good, and your sitting there thinking, "...why does this always win?" It doesn't matter your item set up, if you have the anti tank items, or even if you have stuff that deals %HP damage cause there's a tank item to counter that one item. Oh you got BoTRK? Randuin's omen will slow down your attack along with my frozen heart so your attacks are crawling along so you can't even damage me despite you dealing that HP damage. Oh and now you're dead. Lol. Get good scrub.

I guess it's really time to give up on my favorite champion, Kha, and do what everyone else is doing and just build a tank.
