1) Your current perma lagging build was tough, but man, one wither and you run for the hills not to be seen again for like 15 minutes.
2) With a couple of exceptions, you picked your fights very very well. Who the heck is going to fight against a perma lagging opponent on their terms? Not me.
3) Very hard to be ballsy with a Dwarf Venom Shaman in most cases at hero. People don't stick around long enough when maldicted, and no way to lag them into it. Shaman are vuln Melee, their defenses, for the most part suck.
