Yes I do play for free, that is quite obvious. And no my Internet connection has not been unstable, since that is something I pay for (if you get what I mean). And how do you imagine all 2-3k ppl on the que to stay and stare their monitors for more than 3 hours so, when the server goes down again, you to be the fastest to log back.
Well couple of things could happen. With the "donations" they are getting, they could have kept the 2 servers and merge RDF and BGs (Strangely the company that has created the game that you are not paying for to them, has done exactly that and it works). They can also make quite a few improvements on the server taking examples again from the company they are leeching from. Like having the raids/dungeons and battlegrounds on separate smaller machines, which are not he ones that keep all the continents population. Or have an infrastructure with shifting loads, since "The Nexus" does not have that many players in it, opposed to FoS/PoS.
There are solutions and improvements that can be done if the staff actually waned to do them instead of forcing you to pay for something they have not actually created.
The biggest problem of all of that is that they are forcing you to do that. The merge, not making any of the above solutions is exactly that. I can be proven wrong if they actually addressed the community with answers and explanations - none such are present (except that you can obviously skip the que and be added to the already 12k people by paying). You do realize that if there are 12k players already online and the servers cannot take more load, you should not be able to connect, but you pay and you connect - that would have been fine if they actually announced it (but its a hidden scheme).
If it is a "donation" it has to be done out of generosity by the people that want to (I would if I am not forced to). The amount should not be fixed and put against certain benefits. Thats pure payment, not a donation.
Noone can complain if they say things are they are (or give explanations to problems and posted questions):
We offer: Queue skipping for this much money
We accept donations from happy people that want to donate and help us maintain the server.
Simple as that...
