From your news, it says:
For your efforts, we’ll be awarding a piece of Glorious Hero’s armor to the top 20 players on both the solo and team arena leaderboards. The top 100 players on each leaderboard will also receive a mini llama. The cutoff time for the current leaderboards is 2 December. At that point, the new build goes live and we transition to the new system.
you know anet, people’s rank in soloq fluctuate a lot, becuz it is yoloq has too much luck factor (i would say 50% luck 50% skill)
For me, yeah, i hit the rank inside of top5 more than 3 times during past 5 months, but usually rotate rank within top100. because sometimes i play carelessly Becuz i love to drink and play and do chatting rather than playing. There is no point you reward only current top20 people. Personally, I was even be able to keep myself always within rank 20 by playing just one round per 2~3 days for more than a month before. i just found no point of doing it, so just stopped doing it, and played just alot as much as I wanted to play rather than one per 2~3 days. I think many top-tier soloq PvPer would do it (playing just lot as much as they wanted since realizing keeping soloq rank is meaningless) unless he is just very crazy at keeping high rank only. And that’s why people rotate certain range bracket a lot.
For soloq you have to reward all top100 people a piece of glorious armor, and reward all top200 people mini-malla. or just reward any1 who hit top20 once, you can get data from following website: gw2score.com/PvP
You will see a bunch of people, who haven’t played for a while since hitting high rank just once, playing only one match to get back to top position at the date you reward those things, which is definitely terrible.
