I guess I'll start;

You all want me, knowing I will hurt you, I'm oh so flattered you think me a virtue. 

If you let me in, good and bad times I will bring, I've won more battles than any man or king.

Sometimes I'm dark, sometimes I shine, some think me a curse while others think me divine.

If you guess my name, then I'll raise a toast, you'll be with the one who invites me the most.
