Alright, let me explain why this all doesn't make sense to me.
End the Ranked/Unranked JAZZ.....
It's already been explained why this doesn't work. It's there for a reason; to not mess up progression.... I know the rest of the suggestions basically say remove it, but leave unranked for the modders, and test server.
Show ALL SERVERS ALL the TIME!
They do.... Did you check your filters? Seriously confused, but I guess that has to do with the first part? You want all the servers to show on one list? If you want to REMOVE the filter option, then you sir are a silly little dictator. Either way I disagree with your first part, so I disagree with this.
Classes - make all available at all times
Uhh... Do you mean having all classes show up right away instead of waiting for the server to load more players? It really does help some slow loaders get a chance at not being a rifleman. If, instead, you want 32 snipers vs 32 snipers.... go play Call of Duty... or Battlefield... or you know, try firefight mode.
Weapons - make all available at all times (configurable Scopes/Bayonets)
This would be cool in some ways... except some people payed to get them early... also, some people played long hours to earn them. Either way, it's like telling someone "Hey, some new players are annoyed that they have to earn/pay for it... so we gave it all to them for free." It's not gonna go down well. Also, It's kinda cool to see the variety created because of this.
Finally, allow users to SAVE their weapons selections and use that selection in all maps!
Uhh, what? Are you just annoyed by having to click a few more times to customize your weapons, or are you wanting a CoD clone like weapons selection and customization screen? I personally hated that part of CoD... specially because you couldn't tell what your team had set up their guy to do... and suddenly one is geared to assault. Are you sure you don't want to play CoD?
RO2 is not CoD, BF, MoH or any other silly kiddie carrot chasing FPS.
WAIT!? You want it to NOT be like CoD...Doesn't sound that way from a lot of your previous suggestions as far as I can understand. I guess the "carrot chasing" is the part you mean here, but you did just prove the point that most successful games have this "carrot chasing".
Let's be honest here, it's just a reward to players who play the game a lot... and isn't that a good thing? I want more people to play this game more often. If giving them a carrot helps, I'd start asking were I could donate some more carrots. I currently barely play the game.... missed out on almost ALL the double exp.... and I'm level 89 and I have most of those carrots. It's really not that painful to me, and I don't feel angry whenever I see someone 99 with more gun attachments then me. Why does it anger you?
Let the players Play - Not Chase Carrots!!
Yeah, but what if the players won't play without the carrots? Plus... it sounds like some of your suggestions have nothing to do with carrots, though I may be misunderstanding them... Really, the best thing you could do is prove your point. Get a server popular that plays this way. You might need a mod to do some of those things, but proving it can be modded in would help prove your point. That's all I can suggest to you.
