Since you want to persue this here i will assume you are allowing off topic discussion (ish).
A game is a complex system with complex mechanics to it. The most important parts of this are the blood, and the heart. The population (blood) needs to flow through a game in an unrestricted way. Eve is in a state of existence that the blood is told to go here or there, and the result of that is part of the game no receiving the nourishment it needs. In this case, those parts of the game are the many corporations trying to rise up and make something new.
In all cases the blood needs the heart, and the heart needs nourishment from the blood just as it carries that nourishment to the rest of the body.
Imagine you have two situations, the first is that which is an industrialized product called population / players. They follow exactly what power block A says, or they have to go to power block B and do the same. In both cases the requirements are basically the same (for example, mandatory cta, no mining during pvp ops, etc ). If they reject both they return to high sec to get reject access to parts of their game relative and desired for their progression level.
The second situation is many entities, with different levels, requirements same content access, but different requirements, personality, and levels of development in that. You hae many options to branch out and find a place that fits you well and are not forced into this industrialized homogenized factory like style of game play (ie you dont play eve to make power block a rich you play to make your corp rich (there is psychology behind this that is extremely important to the game, and these points so please take this with great emphasis).
In essence the game is being played like the above. Power block vs power block, but its all a false dichotomy because in both cases you do the same thing, you just have a different set o text aside your name.
Thus, as a result of the lack of choice, the availibity of personality types in combination to access, you have no desire for heart (corps) to pump the players in a direction, and no energy (life force) in the players for them to carry through the body (engaging in new exciting, inspiring concepts).
Thing of the many entities in eve that existed over the years that did new, exciting things. From bombing people suddenly on gates and unique styles of pvp tactics (like forsaken empire had). Even bob implemented many styles of combat over its existence . These things, these forms expression are all but fazed out of the game. The only one i have really seen after 2010 was red frog (shout out to you guys for a great idea!).
Breaking up the alliances into smaller alliances will help stop immortal entities (like goon, Legacy, etc) for existing forever. But more importantly they will instantly provide life to the game by having more targets to shoot at. How can you expect people to want to play eve when they have nothing but quiet corps full of alts to play with? the only ones that do not are the ones that have collected themselves into those large entities.
As for the topic of skill points
There is an important note to be made that should be brought up in a single question.
How quickly do people get tired of the game because of long training periods?The answer to this question (answered by testing or popular opinion) will tell us if for sure we should reduce hac requirement from cruiser 5 to cruiser 3/4.
This has a huge impact to retention rates.
