I know this will probably be moved to suggestions but whatever. I was watching the youtube videos of the old beta PvP and it simply looks amazing compared to the current PvP for many different reasons. I for one do not like the current PvP because it really lacks customization and it gets old really fast. Second, it really lacks concrete strategy, all it is IMO is a chaotic spamfest where the guy just puts a crapload of bombs and then proceeds to spawn kill everyone. This is just my opinion although feel free to state your exp with current PvP. I know OOO will be coming out with some more PvP variants but I highly doubt they will be like beta PvP, and more arcade game style.
Of course when someone ever talks about beta PvP people complain about balance issues, saying that one guy will come with divine avenger and automaticly win. I have a solution for this.
Match the players according to what tier they are in. The scoring system and leader board point systems are not a problem the way they are now and would work fine if this was integrated. So technically a T1 player could be higher in the leader boards than persay a T3 player because each tier level would award the same amount of exp points for leader board. This can also work for teams and guild matches not just for FFA
T1 plays T1 players
T2 plays T2 players
T3 plays T3 players
This is just a hypothesis tell me what you guys think
I'm sure the developers haven't discarded the "brawl" mode for PvP but most likely are polishing it.
As you said the best way to implement this would be to either limit the "star" equipement you can use on a battle (for example, channel 1* allows you to enter only if you have 1* equipement or less) or to limit bonuses on the swords (for example, all ASI CTR and Damage bonuses are negated and a leviathan only does slightly more damage than a calibur).
I personally love the minigame approach more, but I guess older players deserve to "show off" their hard earned stuff to other players face.
I hope egos don't start skyrocketing after "brawl" PvP mode is released... (like in so many action MMOs)
