In my opinion, this is not the way to fix the problem with faction members being inactive, or in any way increase the quality of RP on the server. It only limits people and forces them into hard decisions as to what they should RP and what not to.
With the ability to have 4 different characters you leave more space and give more opportunities to people who come up with different and fresh ideas of RP. Say if I had two accounts only, one in the SASP and the other one in some street gang. I enjoyed and loved both of my characters but I came up with an idea to create some new type of RP, I wouldn't be able to do so because I'm limited to two characters only. The result of that is even less unique/interesting/fresh-new RP on the server, because in reality major part of the community wants to balance things, for example have one character on the legal and another one on the illegal side.
If I don't feel like playing on my SASP character, I might login on one of the other characters. If I don't have any characters, then I won't bother logging in at all.
The 4th character may be "overkill" but it's definitely useful. However if it's such a big issue that this system needs changing, I guess most people will be fine with 3 character slots at least.
