So this is still being worked out, so if there’s any error in my opinions here are welcome to feedback and suggestions, but…
Comparing the ranking and match making to the system used at actual MTG events (I’ve only been to prerelease events but I assume this is close to if not the same system used in all of them) it seems there are a few things we can do in order to break up tie breakers, match making, non event decks, time zone issues for node refreshed, etc that all can be fixed with a few changes to the event systems.
Let’s take Emergency Ordinances as the example for this explanation:
Everyone starts just like now with 0 points and a selection for a white, black, and blue planeswalker for a node on an 8 hour refresh. As far as the first refresh on the node goes, very little will change. You’ll be paired against a random opponent, but as far as ranking is concerned, you’ll either receive 0 points for losing, or 2 points for winning. Optional objectives will be addressed further down. When the nodes refresh after 8 hours, this is where matchmaking will be adjusted. If you won your first matches, you have a score of 6. You will ONLY be matched against people who also have a score of 6. Fours will fight fours, twos will fight twos, and zeros will fight zeros. Adjustments can be made so zeros battle twos if there aren’t enough opponents, but otherwise you will be paired entirely against people at your same tier.
This will solve a few potential issues, decks that do well will be paired against other decks that are also doing well, which will help break ties more than the current secondary objectives will. Additionally, after the first refresh the system will no longer look at planeswalker level when determining an opponent, it will ONLY care about score within your mastery tier. So if you’ve used a level 20 planeswalker in platinum to try to coast to an easy victory, that will no longer work. You very easily could be paired against a level 60 planeswalker on your second refresh. This will also mean that you’ll be paired against decks entered into the event, since it will be looking for someone with your same score to pair you against.
In order for this to work, however, the trade off will be that if your node is not completed within the 8-hour refresh window, you will not have the opportunity to complete the first match and will get a 0 score for all incomplete nodes. This is the only way I can think of to fairly score everyone and make sure someone doesn’t just wait until the last refresh to complete all matches against opponents who have mostly lost their matches.
As far as secondary objectives, these will be use entirely for progression rewards, and will be worth more toward progression than winning the match, and full progression would not be possible to reach by only winning the matches. For example it could be:
White Node:
2 points - Win the match
4 points - Energize 5 or more gems during a single fight
1 point - Cast no supports during a single fight
In this case your secondary points would be awarded even upon a loss to encourage players to use energy or complete alternative objectives. Additionally the rewards would need to be adjusted and balanced between progression and ranking. Possibly adding a rare from the current set as a high progression reward, and eliminating mythics from ranking, and having that award entirely crystals and maybe packs of cards, but no guarantee of a rare or mythic rare card.
