Already tested it and everything works fine. Even players who are not good in duels become more efficient in combats. Anyway, there are skills in dueling aside from lag shooting when it comes in DMs. There are still C-bug, two shot bug, running style and other things to develop when it comes in duels.
Removal of lag shooting is not the only features of 0.3z. They added other useful scripting functions, bug fixes, and protection from DDOS attacks ( Which is one of the major problem of our server). I think it would be nice if our community would give a try to this new updated sa-mp server.
This is one of the greatest breakthrough in the history of sa-mp I guess. This update would be more relevant to newbies especially those who don't know lag shoot. As they said in Sa-mp forums,
For every 1 like you there are 9 that try sa-mp and never touch it again because the aim is so 'broken'.
This would be a good promotion of sa-mp servers.
