Will the servers be forced to do the update?
I haven't decided yet. It would be nice if everybody just updated on their own, but if they don't, the global bans will lose their effectiveness (banned players could just jump on servers with the older version).
And is there a serversided option to block timed and impact grenades so you are forced to use primed grenades?
gren_explodeonimpact 0. The timed grenade is effectively the same thing as primed grenades, so that doesn't really matter.
how doees an aials work for primed nades....like wtf m8^^?
You don't need an alias for primed grenades anymore (in fact, the old one won't work, so if you have it, you need to delete it from your config). Instead, just use the menu or manually bind a key to +tossgren.
