Well the replay clearly shows you didnt say it was over @ 30 minutes, but before, and what stops you getting wards for the teams sake? If you are asked to buy wards from your captain and you prolly dont have the type of hero who would buy them in an XP game, you will ALWAYS listen to him no matter what, and your response pretty much sucked to the question given.
You can't compare euro and xp lol...

It's like as if u want someone to support for someone who won't even be able to have any use of wards,chicken.
I believe its totally fine if you can't play supporter and only carry lol. Most of us can't bother playing supporter, because we don't play it in official games and soso so whats the point in practicing playing supporter or playing supporter for someone else. Your not forced to play supporter in xp, its just that, maybe other better players take them before you.
