I just want to share.
If you see your friend online, and playing Diablo 3, be it alone, or partying together….
1. Your PM is left unanswered. Deal with it. You can always check if your friend is playing alone or partying with others, whether the difficulty is Inferno or something else. Shit happens, and killing shits happens, and you know how fast the message scroll up in the thick of a battle.
2. do NOT. I repeat again, do fucking not, go into your friend’s Inferno game without permission. Do you know how much hp the enemies get when a player joins in? Have the courtesy to ask first if it’s okay to drop by, or hey, party together. How difficult it is to ask?
3. do NOT join in your friend’s Inferno game without permission, and then just stay in town without contributing any damage to the enemies. You are being a huge douchebag, and it is not classy at all. Personally, I curse at you and your whole family and let’s just say that I am royally pissed at you if you pull this trick on me.
