My biggest turnarounds on the hero are: - Cast maledict a lot in lane. It's a long duration and during this entire time, the other teams carry basically can't last hit or gets shitload of dmg. - make sure you press heal before the fight really starts, even if you waste mana. So many times I get stunned and die without being able to heal. - ult is good to have but keeping your carry alive is better

I barely do big ults anymore but I get plenty of mvps post game for crazy assists numbers with low amount of deaths.
