There's nothing wrong with the ATR in icing conditions.
I flew it for two years and had several comments from people about it's performance in icing - sadly these people were just regurgitating something they've read by some layman or heard from some 13 year-old expert on pprune.
Yes, they've had accidents in the past due to icing, but these were as a result of errors made by crews, not a fault with the aircraft. Fly any aircraft around in icing conditions with no ant-ice, or de-icing and you're gonna drop out the sky just as majestically as any ice ridden turboprop!
I really liked flying the ATR. It's a great intro to multi crew flying - laid out like a jet and has many good systems / features.
Crosswind performance is very good and I'd sooner be up there in an ATR in gale force, gusting crosswinds than the jets I fly now!
Enjoy it - there's nothing to be concerned about. . . .
