Just looking at the Dotabuffs, I would say in general, play safer. I notice in most of your most recent games, you have a really high amount of deaths. Especially in lower level pubs, if something seems sketchy, don't do it. Even if your teammates are egging you on to do it, and you know better, don't listen to them. It isn't worth going in and feeding a double or triple kill just because your teammates told you to go in.
Also this is hero specific, but I'm not really a fan of Battle Fury PA. I know some people might disagree with me on that, but I don't think it's good just because it doesn't really work well with the hero. Crit cleaves are cool and all, but the item is so expensive, and really all you need to farm well is Lifesteal. She's not like Anti-Mage where she split pushes with a blink on a 5 second CD. PA is meant for manmoding people and surviving. You need things like HotD, BKB, and of course Basher is pretty core on her these days. If you max Blur second, you can still farm ancient stacks with an HotD, and don't need a Battle Fury for it. If your lane is rough, and you can't really walk up and get many last hits, get Basilius/Aquila and Dagger for them. It's not ideal, but you can make the best of a bad situation that way.
