Normally I rarely play DT so on beforehand I apologize if I make any statement which is incorrect but I just base this opinion on the DT I played.
I decided to play DT this time and noticed that I was matched with the same people regularly during the DT. So after the DT finished I looked if this had a certain reason. After the DT I saw that a total of 62 players attended this tourney which is a fairly low number in my opinion. But then I started to count the number of different players I faced. In approx 50 minutes, I faced 14 out of 62 different players in a total of 24 matches. Considering this I can conclude that the player variety is very low. However, I have to add that during the DT most players will just stop playing when things don't go their way or they have to leave. This will result that at the end you'll most likely fight higher ranked players instead of lower ranked players.
The interesting part tho, out of the top 10 (including myself) I faced 3 different players (a total of 4 fights against them), the rest I played ended outside the top 10. The guy I had to face 4 times in total even ended 16th and I started wondering. I realized that the guy I had to play 4 times had a pretty meh DT deck and also a decent counter to my deck, so he would be unable to get a good amount of points while I struggled to win.
This makes my conclusion that playing DT in a low hour can be an advantage but also a pain. (post 2 to continue since I am at 1.500 tokens)
If you play DT on an hour with less players you will see more familiar faces. Thus the more likely you will see the same deck. In case it's a deck which is either a counter or just hard to play against (or even both) you'll struggle to get a win so you'll get a low amount of points.
On the other hand, if you're lucky enough to get the same guy with a 20* hand which you counter and find easy to beat you will just earn points like it's nothing.
I do not know if it's possible but I would like to suggest maybe not allowing people to fight each other more than 2 times during 1 DT. Yes this will lead to fewer matches played in general (I would assume so) but it will probably lessen the problem of facing the same counter deck over and over (if you're unlucky) or the winner of the DT facing the same easy player over and over. This might make DT also a little more fun and exciting than based on luck who you face.
What do the more experienced players think of this (and is this during peak hours also the case)?
Also to add now I can see the DT results:
The person with my 'counter' deck which I faced 4 times has played 14 games in total the entire DT. Meanwhile, the guy above me who played 27 matches I have not even faced once. If I look at this, DT rankings is also a little influenced about who do you face the most and if they have a counter or not which should not really be influencing that much.
@ DUC-Elias : I notice that as well. Your matching will depend on the available players at the time you finish your match (at that exact moment), this issue never was a big problem before when it had a huge player base in '06-'08. The trick here is to have 2 decks which you can switch around during the tournament; by using multiple web browser to quickly set your deck before your match ends. You can have a mono-Raptors deck, while the other can be an attack manipulation deck.
