Same exact thoughts, I have played every day except the 4 days I was on vacation, have done all my daily and weekly tasks, seasonal challenges, all but the co-op seasonal task, and claimed the daily shop Tix. I just completed today's tasks, this week's tasks and the new seasonal challenges and claimed my daily 100 shop Tix, I still need 9,185 Tix to complete the pass. As long as I play every day, I think there will be enough to complete the pass but in absolutely no way is there an "overflow of Tix" and it's actually kind of irritating that's the sentiment they have.
I really question where they came up with the fact that people are overflowing with Tix. Are they just looking at people's Tix balance without checking if they own the premium pass, or have spent SVB on Tix, or just aren't claiming things they don't like from the pass? Because those are the only 3 responses I've seen from people who say they have thousands of Tix left over. Anyone who is actually trying to complete the pass in full, which is normal behavior in any game that has a pass, still needs thousands of Tix to do it.
