AWP
I believe the CS:GO built-in kill replay still works properly, could you elaborate on what you mean?
Remove the rtv cooldown when the map changes
As Majesty has already said, the RTV cooldown is there to ensure that maps are not changed off immediately as they are voted on. The map was voted on for some reason or another, no one would get any playtime in if maps are RTVed off the instant they're changed to.
This is something that can be looked into depending on user feedback, although the server is the AWP server, most people are there to practice/play using AWPs, I have my doubts as to how community response to this would go.
TTT
Introduce new !RTD rewards such as zeuses, bumpmines/tac aware grenades, 1 hit knife.
Zeuses are scanners in TTT, I'm assuming you mean that when you say "zeuses". If so, it could be a good idea to implement into RTD at a low chance. Tactical awareness grenades will be added to RTD SoonTM. Bumpmines will not be added to RTD due to the potential for griefs/RDMs, potentially as a T shop item but not as an RTD item. 1 hit knife could be interesting, I'll look into it sometime.
Low-grav rounds can easily cause map exploits and glitches to happen, they will not be implemented, as unfortunate as it is.
Add bump mines/tac aware grenades to large maps
We're looking into adding tactical awareness grenades in the T-shop and in RTD, however bump mines will not be added for the reasons Majesty already stated. It's too easy to cause griefs. It has potential as a T item, but even then it'd have to be carefully considered.
The following are caused by the CS:GO update breaking the plugins we use, they will be fixed as soon as possible by the Tech Team:
Add back the point system
Bring back the !ws and !knife command as well as adding a !glove command
