Mechanically i'd argue no IGL can match him and calling wise he has been VERY good lately. I'd say rn he's top 3 IGL itw.
He is the best igl in terms of mechanical skills. But sometimes, he made some questionable decisions that Boaster would rarely make, and once he is tilted, it's hard for him to adjust and adapt to the enemy starts, which is why if Fut didn't get any momentum, they lost a winnable round, and this is also why we see a lot of comebacks after they switch sides.
speaking english =/= being able to com in english as n IGL
Look at Redgar IGL-ing on TL, it was so rough i felt so bad for him. Going from IGL-ing in your native language to a completely different one is very hard, unless you're 10/10 bilingual and can think in both languages at the same speed (which is obviously not the case for MrFalin) and on top of that being used to express your thoughts as an IGL after doing it in your native language your whole life really
So nah
