I agree with what Konr said, especially the comparison to Pledge. What I sometimes feel is lacking is tempo. You'll talk about something that happend on mid while teams are gearing up to push last.
I also find that when you are describing or analysing something you get to caught up in formulating the words that you miss things that are happening. Just now during esea lan you missed a medic drop, due to this. You should imo give more room to your co-caster as well and not just for the in-depth analysis part.
