This was absolutely not the problem at all. While he may not like shadow shaman after 1 game, or ever, his play on him wasn't the problem of the game. Too many things went wrong that game, starting with the hero selection (not ss), to pretend a off-lane support had anything to do with it.
Welli gets stuck sitting in the fountain looking in the shop, and I get that, the shop is overwhelming as fuck. Already 110-ish heroes to get an idea of what they do, add in all the items and you want to stab someone. BUT -- forget all that and learn the basic items and how to use them effectively. Wards wards wards.
Vision is like 70% of MaddenGAF problems, learn it early. It's why I hate playing mid, we usually lack the proper vision to play it well and go out for ganks without leaving yourself vulnerable.
I wasn't blaming or pretending to blame a off-lane support for what happened. I was just saying doing random draft for him might have been a problem, Eznark explained the logic behind it and I see now.
I take partial blame because I need to learn everything with all these heroes again, I use to off lane with DP in the past all the time with GAF and nothing was ever said about it so that's what threw me when you said I shouldn't pick her, but our lineup was pretty bad all around.
Regarding the last part I see what you mean, no vision got me wrecked in mid due to pudge coming around back to get me which caused the tower to get pushed and then it all collapsed from there.
