I didn't say that they're saving strats for TI.
But on majors teams are putting way less effort and have lower passion to play than on TI. Teams aren't playing at their full power, especially top ones, because they don't care so much.
CS is completely opposite. Teams are fighting for every title. IEM Katowice is important. IEM Cologne is important too. They're fighting for winning BLAST, winning DreamHack as much as they're fighting for major titles.
