I've read 18 pages of complaining and I can't believe how many old names gathered up to complain about RS5, in fact, i have never seen such users united for anything until now. Admit it, RS5 brought an union. :P
Hey there cofi and leon, I hadn't heard about you for a really long time!
While I was present in the very, very, very early development of RS5 for a really, really, really short amount of time, I had read and understood the plans that we as developers had to follow in order to get to a new gamemode. RS5 is not wrong, it's incomplete. If the roadmap hasn't changed from then, then I can assure you that there are lots of functions not added yet, coincidentially most of the criminal scripts parts.
You can ask, why were the cop/firemen scripts introduced over the criminal scripts? Well, the cop system is not really hard to do if you have a base. While of course it had to be a total rewrite, we knew exactly how should it behave and what it should do, and to be honest, it was not a great innovation since not that many things have changed apart from a very few things.
On the other hand, everything that was planned for the criminal system was purely new and we had no base to attach to, and I am sure it was a great challenge for the developers that had to continue with it, and that might be the reason of why such functions are not still in. As I said, I left in early development so I cannot say much more and maybe I could be completely wrong, but this is my point of view.
I do agree with the fact that there must be actions soon or else the damage done will be unrepairable, however I am not really in a position to complain or ask, I am barely a part of the community right now, compared to what I once was, I am just commenting stuff here.

P.S: I agree that the criminals are in a really bad position to do anything. Yes, there are basic roleplaying commands but the main mode on the
current state is completely sided for the cops... In RS4 it was like this, however, RS5 was meant to be introduced to create a balanced opportunity for all the three "factions": law, civilian & criminal, but as I said, I trust that this will defenitely change once the scripts are 100% completed.
Now, don't blame the developers either. They have done their best so far and I am sure if they could have done any better they would have done so. RS5 development started too late (and I myself are guilty of that),.
