Thank you morphine, Charley (again), Panzer, Sevrin, TheKing and Ferrari for your comebacks. It helps me and everyone here to see it from another perspective.
Honestly, I felt that Doom had a very serious point on that debate when he mentioned VU as a dominant clan that has an incredibly high amount of players on its rows. However, after reading this whole topic, the claiming of that a restriction / applications closedure would make a positive impact on VC:MP emergence of new clans is totally senseless.
On my actual view, locking applications will not only help at all, but will even make players leave more than they do instead. The reason is simple: You all have mentioned how current clans like VU / MK / SS / OSK (at my time) interact with a kind of players that are newbies to this game; the majority of us (even more the latinos like I) had to struggle to understand how the mecanism of the community is, I remember myself on my first attempts on Mega War and how I had none knowledge about the basics of a VC:MP forum.
I had to struggle and spend much more time than in a normal game to get into the rythm of the community and joining a clan was a great help for myself (OSK in my case because of my language, VU in case of majority), without whom I'd probably not be here.
The style and structure of clans and how their goal and objective make them so dominant, apart from the time and effort spent on building such a thing, make me think that if it weren't for them, none of us would be here.
To set my point, I want you to imagine if dominant clans closed applications - and match it to the current player base and projects in emergence: none of the newbies would be really able to join a clan frustrating them (as you said, most of players remain here because their clans are greater than VC:MP itself), very few people would be really capable of building a new clan from the scratch and would leave the game inmediately. It is gonna hurt VC:MP more than it already is.
The thing is the following: nobody understands that it takes time, and there's no "divine intervention" to help this game rise. It takes a lot of effort like VU, ULK and XE rised back at 2008.
Once again, thank you all for your contributions to the post
