Just faced a Tryn, Malph, Jayce, Xin, Morde team. My team wasnt the greatest and I played a bit sloppy, but they seemed to do incredulous amounts of damage for being so tanky.

Any tips for beating tanky teams like this?

Madreds Bloodrazor

lol i thought this thread was about tanky teams. That is obviously not true. Tryn is easy to burst down with 1 stun then activate randuins during ult. Xin is destroyed with an ignite malphite should be melted by your ap carry or he can build mr and lose dmg. And morde is tough to deal with but again ignite or executioners calling does wonders. If your team did not have an executioners calling you asked to lose the game. This comp is not hard to deal with as they are all melee close range champs. Use range and heal debuffs.

yea, just burst the entire team and you should be good!

if its that desperate, madreds bloodrazor.

They are only ouch if they get fed early game. They don't get fed, they're only semi-tanky with meh damage output. Beat them early by playing smart and making every CS/kill count. An on-to-it jungler will win the laning phase and carry through to a swift victory.

Just get Armour Penatration?

Tanky teams need twice as much gold to win. If you don't feed and build a little survivability like frozen mallet or zhoyina, you'll win

Madred's is not the answer.

You do realize that the dmg is magic damage, NOT true damage? That is an extremely expensive piece of gear.
