What I noticed about the other team is that no matter how long the game went on, the only champion on their team buying any sort of anti-damage items was the tank. Everyone else on the team played as if our powerful damage dealer did not exist - as if he posed no threat to them! They would definitely have stood a better chance if everyone on their team bought some anti-damage items.
Here are some tips to remember when your team is fighting a strong physical damage carry:
1- Reduce their damage!
If an enemy carry is getting tons of kills, you will need to resist that carry's damage type. This means that, in addition to your normal item build, you would have to add in some armor. It does not mean that you have to drop all of your plans in order to buy a 300 gold cloth armor, heavens no! Just one armor item will suffice. Your goal is to survive just enough hits from their carry that your tower or teammates can come to your aid (and even better, destroy their weakened carry!).
2 - Never go anywhere alone. Ever!
One of the major strengths of a strong physical carry is that they can solo any champion 1v1. If you are ever caught in the jungle by yourself with no one around, and an enemy physical carry finds you, you can kiss your safe trip home goodbye! The enemy carry will make short work of you, as he/she will be incredibly formidable in auto attacking to a point where it would be silly to think that you could escape (or let alone, survive).
You will need to make friends with your teammates so that if you ever encounter an enemy carry, the two of you could possibly snare, stun, or slow just enough that the two of you could make it out alive!
3 - Focus Fire their Carry!
Your team can turn the tide of battle by focusing him/her when the battle starts. Once their carry falls, the others will only follow suit and fall, too! Always, always, always focus the enemy carry and use disabling spells such as Exhaust and Ignite when you're in a big team fight! He/she should not be able to survive much, since carries typically have very little survivability. Take advantage of this and destroy their carry in one fell swoop!
4 - Buy Anti-Carry Items! (When you're tank)
An extremely useful item to buy when you're a tank is the ultimate anti-carry item, Thornmail. This handy dandy item not only gives you tons of armor, but it also reflects a percentage of physical damage done to you back to the attacker as magical damage! Another extremely useful anti-carry item for tanks is Frozen Heart, which gives you tons of armor, some mana, cooldown reduction, and reduces all surrounding enemies' attack speed! Lastly, Warden's Mail severely handicaps any auto-attackers by reducing their attack/movement speed when they attack you!
