You need the right combination of word choice, volume of speech ,rate of speech and tone to hype up the audience.
Scrawny merely speaks louder when he tries to hype up the viewers. It feels so fake and artificial. I simply can't get excited when he casts.
If you want to know what is true hype, watch anders & semmler at their prime (2014-2016), henryg & sadokist (2017-2018) or ddk & bardolph (eleague boston major). You can clearly tell the diifference between top tier casters and normal casters like scrawny.
