I also really like the new patch because it was probably the biggest change to Dota 2 in at least 3 years or so. It is also pretty exciting as a viewer of the Berlin Major that started today, because even the teams that were the best in the last few months like Team Liquid and Gaiming Gladiators still need time to adjust to the new patch and it is very much possible that other teams could be stronger now with the new patch.
Of course this makes it also harder to make some good predictions for betting. I mean if you look at the matchup of Gaiming Gladiators vs. EG earlier then this was obvious again. In the first match GG totally stomped EG, so a win for GG as most people would have expected i would guess, but then in game 2 EG was very dominant and won convincingly.
It is probably best to wait a few matches and then start betting after we have a better feeling about how well the teams are doing with the new patch.
