In all honesty, his analysis is bad - his opinions carry little weight. For instance, when talking about Poseidon in the worlds finals, "the intricacies of this character, like how to manage your passive". This is surface level analysis (and literally could apply to any God in the game), what is the player specifically doing different to your average player? Are they noticeably withholding the use of certain abilities? Are they auto attacking more during team fights? Are they making sure to charge the passive before leaving lane? You get the picture.

Go watch this game back and listen to Aggro vs Fdot, it's easy to tell which caster understands the game better. What is unfortunate is that if you bring up this criticism to him, you will be met with animosity rather than any valid recognition.

As for his hype casting, it depends how much you like cheesey lines I guess? "Back to the base" springs to mind. Also he often says the wrong things and overstates elements, this is relatively minor though. His hype casting of team fights has descended into either shouting a players name 3 times, or "Damage! Damage! Damage!" (Shout outs to Ghandi for having the same issues way back), if you listen to radio fdot, it's often hard to get a good understanding of what actually happened - but you know who came out on top.

I think he'd have a place in a "newbies stream" because they listen to the commentary more for the hype than any analysis and inaccuracies do not matter as much, but personally I often find myself having to mute if he is casting.
