Hey, I am currently only playing EU and rank 7, and there any Legend players who would coach a poor climber? :) I am sick and there aint so much to do without playing Hearthstone :/
So you make it to legend once? What's the difference? You now have a cardback. A lot of us are trying to reach legend, but you should try it on your own. Just keep grinding every season and you'll get a rank or two higher every season. It's not like there's a shortage of time because you're sick. And plus, it'll feel way better if you get legend on your own, because if you did it with coaching you pretty much don't deserve to be legend.
