I have seen Astralis tilt a little at the ESL Finals in Odense, I was there in the audience, it was painfull. But this happens more to liquid when they are not confident, they get into a mode where they make lots of mistakes.
Same can be said for EG, when things go bad, they usually go worse than they "have to".
Would love to see some development in map pools for all top teams to keep it exciting, Liquid mentioned that this is a goal for them.
Worst thing is, we will have to wait for like 2 months before we got the major, so looking forward to seeing some new stuff after all the teams finally have time to develop some.
