My idea is this.
Improve rewards as follows. Top 5% of players in each faction in a campaign get Masters weps, or even vMA weps, even if not these rewards, maybe other rewards that are very very difficult to nigh impossible to get., which are unbound (and thus sellable). But, and here's the but, if you swap factions during a campaign, you lose ALL end of campaign rewards from that campaign. From your whole account. No transmutes, no nothing, except the AP which you earn. Apart from that, bupkiss.
The reasoning behind this is as such....
-PvPers no longer have to do PvE content to get the really good gear (and lord knows they like to complain about it, loudly and often)
-These weps can be onsold for gold, which PvPers tend to be short of, because pots.
-The reward for the top 5% of every faction goes some way towards mitigating any faction stacking in order for end of campaign rewards, whilst not being incredibly restrictive, ie you don't have to spend 150 hours in Cyro each month.
-The loss of all rewards at the end of a campaign enables those who just like to have a good fight and/or push the map to have that, but at a price.
-Hopefully this will keep the map moving in off-peak, so people who play outside primetime can see both action and maybe even fight with chums.
Feel free to pull this idea apart. I welcome constructive, thoughtful criticism. Especially good would be folk who do want to faction hop or play in off peak.
I don't put forward this idea because it would benefit me (probably the opposite), but because PvP in this game is starting to look pretty unhealthy.
