No you shouldn't get advantage because you are with a friend.
I think it is highly unfair and somewhat rude when some says "I'm duo with ____ so we MUST have bot"** even after you called adc or support before them AND is also in a duo with another buddy**. Even if you are first pick in a ranked or draft! And you tell them no and you pick the role you got first but they decide to see if you will leave the game so they pick all supports. No! I am stubborn yes! I shall not leave! Infact why not? I don't care this should be fun! In the end they left. GOOD!
Just because you are with your buddy or because you are in winning streak and you think you deserve a certain role doesn't mean you can have whatever you want! NOPE! I don't care if you are in Skype with your buddy either!
Heck recently I was with my friend and we wanted to duo bot and I did indeed called support first, not only that I was first pick. Also I was in a Skype call with my buddy! I DID NOT freaking say "I deserve this lane because I'm with my BFF and we are on Skype." cause really that is just stupid. I call my role first, I get it. You call your role first, then you get it. Unless you actually can't play any other role then please speak up, maybe I'll be nice and give you what you want.
It just bothers me like crazy that stuff like this happens! Also when you get put with a premade group of 4 and they are all buddies on Skype. They say "Uh you aren't with us so we demand you to be this role because you don't deserve to be this, you loner." This is actually something someone told me. It made me upset! I calmly explained to them "Hey, I'm not really good at this lane I hope you don't mind horrible ganks." and their only response is "Then why play? If you suck don't play LoL." or "It's ok we'll report you for feeding and not communicating with team.".
1st I play because it is entertaining. ISN'T THAT WHAT A GAME IS?!?! Entertainment? To have fun? Feel good? No? K. 2nd Yeah I care that I may suck but how else will I learn in order not to suck? (Yes I practice in AI games too) 3rd Are you kidding me? I DEMAND JUSTICE!
Sorry about the rant but has anyone been annoyed by this? I wish something could be done about this.
and
can be a bitch when both ult at the end of a teamfight and the enemy is running. Once is standard, both was overDOUBLEkill.
