Mejais for Tanks

You stack armor and or mr while taking dmg by enemy champions (while taking dmg for your team). The important thing: If you die, you lose a part of these stacks. So if your enemies dmg you but dont kill you, you get stronger and stronger. And when they kill you permanently you get weaker. There could also be a restriction, that u can just stack if u get an amount of dmg in a specific time (for example 30% of your HP in 4-5sec = 2 stacks = 15 armor or 7.5 mr). Another possible restriction is for example, that u can just obtain the stacks if u r next to allied players...
