[Inquiry] Progressive Content vs Eternal ICC

About Me:
Firstly, I am a long time private server player, and have played private servers for Vanilla, TBC, and WotLK. I have also played every retail expansion to date, though little after WotLK.

I usually favor playing on Vanilla servers, however, due to my recent decision to go back to college to get my master's degree I do not have the time to invest in the Vanilla WoW playstyle. Due to my time constraints I have decided that WotLK would offer the best balance of challenge, competition, and grind to coincide with my new playstyle and schedule.


Now moving on to my inquiry:
Does Warmane - Lordaeron support an "eternal" progressive state in any form or fashion?

While research and reading about various WotLK private servers I stumbled across how "Dalaran" supports a system in which you cannot progress into the next raid tier without first completing the previous on 10 or 25 man.

I have seen that Warmane - Lordaeron supports a system to increase the raid damage, health pools, and other aspects to provide a more challenging raid environment which in turn can offer a portion of longevity to raid progression.

The main purpose of my inquiry into this "system" is that with my time constraints, I have no idea how long it will take for me to level to max, and I do not wish to only raid through ICC. I wish to go through full raid progression (Heroics > Naxx > Ulduar > ToC > ICC > RS).


In Addition:
I have no wish for Warmane - Lordaeron to change their philosophy or plans. I am simply inquiring on some aspects of the server that I was not completely clear on. If you can give me any other information that would help solidify my decision, it would be much appreciated.

I also have no intention of playing on Dalaran due to immense bugs, dead pvp, and increased leveling.

....and sorry for the longevity of this post. : )
