If nothing else it'll just bottleneck the XP grind zones the day after the cap goes up.

Ah, ok, didn't know that. Still, I would think that if you get exp for kills, but

a) only if they are relatively close to you in level, and
b) only if they are a legit enemy team member, and
c) only if you haven't killed them like x times before in the last y minutes

it might promote pvp over pve to some extent without being hugely exploitable.

I don't think impacting xp positive or negative is a good idea for promoting PvP. PvP in itself slows down xping.

Level capping is somewhat interesting. It was annoying as hell to read all the PvE crazed exploiters bragging as if leveling the fastest was something PvPers cared about. It might force these people to actually /gasp PvP. While there would be some consequences I don't think it would be detrimental long term, unless items that get removed form the game were taken out before people got to those levels.

they would just level up alts at the same time

possible.

So?

The point is to keep basement dwellers from outleveling everyone else by playing 20 hours a day for the first month of the server.

If you remove the possibility of massively outleveling the rest of the server, there's no incentive to poopsock during those first few weeks. That keeps people competitive without making them feel like they have to dedicate their lives to the game right out of the gate.

I think you'd get a lot more participation from Blue if people knew they wouldn't be blown out of the water if they didn't switch over to Teams immediately and grind XP nonstop for weeks.

I'm not sure I see where this is coming from... since when did a typical blue player not thrive on wanting to get ahead of other players on the server in some capacity? Take the EC trader as an example...everyone is climbing over everyone else to try and amass more plat, to keep their "wealth" on an upward curve ahead of inflation.

There's also no reason to think that a typical PvP player is going to be well ahead of a blue player in terms of an XP grind.

even with a level cap progression you're still only benefitting some class of players whose playtime lies between the super casual and the super neckbeard.

and there absolutely is incentive to poopsock: keeping the more casual players out of the great leveling zones and preventing them from getting the good gear. keeping somebody at level 20 doesn't prevent them from being an asshole PVP griefer for 18 hours a day.

besides, this would only put a band-aid on the problem and provide a minor setback to people that have a ton of time to play. who do you think will get all the great gear when the level cap is gone? and who do you think will be prevented from getting all of that great gear? how will this affect the PVP scene at higher levels?

this idea will change very little at the server launch and nothing in the long-term

I've begun referring to such things as "no child left behind" moments.

(Says a person who takes 3 years plus to get to L54. "Go on... leave me... I'll *cough* I'll only slow you down!")

Terrible idea
