Since the release of Shadowlands (Before I started playing), Agents have been pretty much locked into Rifle as the only option for weapons, our current Rifles are comparatively very poor to most professions options and there is nearly always at least one thread around with Suggestions for a new better rifle to allow us to perform better.
As far as I can see things, different Agents want different things from their rifles, Some want to have more specials to Alpha better, others want it to be hot-swappable so they can use PE Hot Swaps, and others want a better more Viable weapon for PvM, preferably with a much better Crit Modifier to go with the recent improvements to Critical Increase.
So overall I believe every agents still wants/needs better Rifles.
