I posted my thoughts on Jedi's idea which, ultimately isn't feasible, on the ACVD arena. Here is a quote:
@Jedi: The original incarnation of this arena was exactly that. However, due to an extreme lack of interest, it was changed in favor of the new system, which makes it much easier to get matches and activity. The major limitations with your suggestion is that it relies on players going through significant work before they get the chance to experience the Arena. And for many, they aren't willing to commit until they have a few matches first. This creates a catch-22.
Creating an alt is more difficult than one would think. You have to grind money and go through story mode to unlock all the parts, and the biggest limitation is creating an alt does not allow you to carry your main name and reputation publicly. At least, not readily and apparently. And while having anonymity is its own fun thing, there are far more who want to stake a rank and reputation on their main PSN handle than those who want to be anonymous.
Merging the arena comprises of two things: 1. Merging Rules and 2. Merging Ranks.
Merging ranks would follow this formula:
If a player in your arena won a match against a player in my arena, they will be placed at the rank above the highest person they defeated. Currently, the only players in your arena who fits this description is Dissociation and Hela, who defeated Swordfish. This would place Dissociation at Rank 5, Hela at 6 (because he is a lower rank than Dissociation in my arena) and Swordfish at rank 7, the other ranks adjusted accordingly.
If they have no matches in your arena, but are a part of my arena, they would retain their rank in my arena. (Floyd, Bottle, and PDN)
If they have no matches in your arena, but are not a part of my arena, they would be added to the bottom in order of their ranking in your arena (shieldfailure, then heliosophist, then andryrock)as new members to the arena. This eliminates any "first come first serve" ranks from your arena.
The next part is merging the rules. I can say it right now, there is little place where I think the ninebreaker arena rules would benefit the arena on whole, except for solving some of people's concerns with the ACVD arena's top 20%.
My proposal is thus:
Reform the ACVD's top 20% rules utilizing some of the Ninebreaker arena's rules, as they are the most similar types of rules. Essentially adopting portions of the Ninebreaker arena's rules and applying them to the existing ACVD Arena.
The normal Arena: (Bottom 80%, or ranks below 10)
1. Challenge anyone, 1 challenge at a time
2. 2 out of 3 victory (Faster, easier matches for less hardcore players)
3. Ranked below the Elite arena
The Elite Arena: (Top 20%, or top 10)
1. Challenge only the rank above you
2. Two consecutive victories (More decisive matches that rely less on the rock paper scissors dynamic that 2 out of 3 does)
3. Requires a certain number of wins in the normal Arena, plus a victory against a the bottom of the Elite Arena rank according to elite arena rules to enter.
So you could essentially treat the normal arena as a fighting pit for players to enter the Elite Arena, which has more restrictive rules.
These are the terms that make the most sense if an arena merge is to happen. This kills 2 birds with one stone, facilitating a few reforms of the ACVD rules that have been discussed, while also merging the two arenas.
