KT have a lot of momentum on their back; having only lost to SKT and ROX Tigers earlier this split. Unlike other top tier teams like SKT and Jin Air, KT have demonstrated a very high degree of consistency. They excel at taking early game objectives and tower trade offs while excelling through to the late game.
Afreeca have had a pretty decent run for a mid-tier team. Unlike KT Rolster who are very well rounded in very lane, Afreeca are more dependent on their ADC Sangyoon as a carry. Sangyoon excels at team fighting mechanics and keeping himself alive.
All-in-all KT Rolster significantly outclasses Afreeca. They should use their experience, game knowledge and split-second calls to push forth an easy victory. It is very unlikely that Afreeca will come out ahead in this best of three.
Prediction: Afreeca Freecs 35% | KT Rolster 65% (2-0 KT Victory)
