The latest Heroes of the Storm balance patch isn’t going to give anyone a bunch of satisfying new tricks. It’s actually taking a lot of existing tricks away from various characters. Tychus, for example, has proven to be too darn good at not just tank-busting but assassin-busting as well, therefore making him too dominant against too wide a spread of heroes. Murky is clearly dominating, Malfurion is too good as support, and Varian isn’t unbalanced but did have a few abilities that were just not fun to play against.
As such, all four characters have received some major adjustments. Tychus has had his attack range dropped and several abilities tinkered with, keeping his power at his intended role but tuning him down elsewhere. Murky received a wide-reaching nerf to his control and reliability, while Malfurion loses much of the power on his Entangling Roots and associated talents. Last but not least, Varian’s Warbringer has been changed to a Slow effect, as the ranged stun was proving too easy to abuse and led to unenjoyable game states. There are a few other heroes with adjustments on a smaller scale as well; you may want to check out the full patch notes before diving in.
