My initial response is twofold:
Firstly, if it gets people into matches
faster and more often, then I absolutely would love this. If I'm still earning Amarr LP, then fighting on Caldari soil doesn't bother me much- they are supposedly our allies after all.
Though I'd like to mention that if you fight for the faction that's allied to the one you queued for- like in your example of "Queue Amarr, get dropped into Caldari because allies", then it should, IMO, be a split payout- while you are following the Empire's orders, you're still helping the Caldari. Be nice if they "showed some gratitude", so to speak.
Secondly, and this is the biggie:
it's not going to fix disparate queuing. If more people are queuing for Gal/Min than Amarr/Caldari, then it's going to take longer for the Gal/Min players to get into battle than their opposing factions.
As an example, in your OP, you outlined the following queue counts:
Kaeru Nayiri wrote:# of people queued, ready to fight
Min: 45
Gal: 53
Cal: 15
Am: 4
[obvious snip is obvious]
So, the problem I see is that the Am/Cal side can basically muster a whole team and a little bit of change.
The Gal/Min side can muster roughly
six teams worth of players. As it stands most of the time that a "slow deploy" (IE, more than ~3 minutes) happens has one of two causes:
1. There's nobody queuing
at all. Mostly this will happen to the Amarr/Caldari side; IE, nobody is queuing for Gal/Min whatsoever.
2. There's
not enough people queuing. This generally happens to the Gal/Min side, in the opposite fashion of the above.
In the former, there will be no matches- there's simply not anybody to fight. For the latter, there will be long wait times, and fewer matches for those players.
As to why that is... it mostly comes down to the stereotyping that CCP did with the nations of New Eden; IE, the Amarr are religious zealot slavers, the Caldari are capitalist megacorporate mangs, the Minmatar are the oppressed, downtrodden and enslaved (but now free!) dudes, and the Gallente are the MAXIMUM FREEDOM guys.
Because the Gal/Min side is pretty much "typecast" as the so-called 'good-guys', you end up with fewer people queuing for the Caldari and Amarr. With the Amarr, there's the obvious thing of them being, well, religious zealot slavers. Most people take one look, go "eww", and probably pick MAXIMUM FREEDOM or the supposedly plucky but mostly dirty slave people.
They don't look deeper into the beautifully rich cultural identity of the Amarr, and the noble, steadfast nature of the Empire. At the same time, they never really look deeper into the other empires either- the endemic crime, economic instability, and barely-competent leadership of the Republic, nor the fact that there's a very good reason why the Gallente Federation is described as "no better place to be wealthy, no worse place to be poor".
And the poor Caldari just end up coming off as incredibly bland and boring by comparison, despite having a rich culture and background of their own- though I'll admit that it's hard to make a clip that
might be 30 seconds long (I don't actually know, I don't think I've watched the DUST race description clips) actually describe the Caldari as anything but "supercapitalist and also megacorporate".
And this has turned out longer than I originally thought. Oh well, I guess my full thoughts on it are out there.
