Yeah, it would be totally inconvenient for someone to stream unless he is a godlike player to show the world his might!
Anyway I'm gonna play with a few characters, I'll list them so you can recognize your inevitable doom in time
Vegeta - typical WW barb with either Arreat's or BerBer CoA. He is merciless and won't hesitate to use Wisp Projector. He is coming for you... you can't hide...
Ramona - assassin hybrid with Lightning Sentry and WW. She has 50% DR on default and has an option to use Oak ring. You can use Wisp against her and have in mind her WW hits quite hard. She's not afraid of anyone, although barbs are tough to beat.
Sinn - ghost, strongest WW version of assassin. 50% DR, high clawblock. If you are playing a caster, run and don't get stomped because... because. Keep your distance and let her come to you, one mistake can decide your fate. If you are a barb, then she is probably dead.
Odiseuss - max block windy. He will try to stomp you and kill you fast. Expect unexpected stomps, he might go after you even in a trap field, he might stomp you even if you have a barb. Be patient against him.
Fisto - pure hammer with charge/smite option. He is a pure soul who fights against good for the evil and... wait, what? Anyway. Around 1.4k hammer damage, doable match for anyone except barbs and maybe ghosts. Just don't provoke him as a bowazon because he might get angry and charge/smite you down instead.
Windu - hammer/charge/smite hybrid. There is nothing you can do apart from playing it smart and wait for his mistakes. He can charge you to death if you have no block, eats bowazons for breakfasts, wind druids are just a minor inconvenience and barbs sign a peaceful treaty on sight.
Shenron - zealot. You have never faced zealot and it's best you never do. Block helps, casters who keep distance can beat him, but have in mind his charge and zeal hit like a ton of bricks
Playboy_Bunny - team player barb who leaps you to death. Literally. I'm not joking.
