Aptif people want to cheat that badly they're going to find a way to bypass the requirement anyways
I see this "well if people want [x] badly enough they will find a way to get it anyways so there's no point in doing [y] to make it harder" argument a lot and there is a huge logical flaw with it.
Very simply, making it harder to cheat DOES deter many cheaters, even if it doesn't net 100%. Even with the ones who do persevere, it makes the costs (literal $, time, and/or effort) higher per attempt. In my experience, the level cap has been a huge deterrent to cheaters, raising the cost of a cheating attempt from merely the time it takes to make a new account to the effort and money needed to find and buy a level 5 account.
To throw out just a few analogies:
-If people want to rob your house badly enough they will find a way in, but that doesn't mean you stop locking your doors or that you disable your security system, because those will still continue to keep out the common criminal!
-If a hacker wants your data badly enough they will find a way around your antivirus software -- but that doesn't mean that you should disable it, saying that there's "no point!"
-It was a long time before wearing a seatbelt in a car became a legal requirement in the U.S.. Nowadays, you will still have the occasional idiot who doesn't wear one (notably including my older brother, who rolled a pickup without a seatbelt when he was 16 and was lucky to escape without serious injury), but since the law requiring seatbelts passed, deaths and injuries from car crashes in the US dropped dramatically.
P.S. if you use this flawed logic to argue against gun restrictions, the same stuff applies! I believe that there are legitimate arguments against gun restrictions in the US, but this is not one of them.
AptNA DM is more dead than now from the level requirement than it ever was because some 12 year old decided to test his premium cheats there.
This I might agree with, but I'd need to see actual data on numbers of cheaters and the overall DM playerbase.
