This is true, especially at lower levels when your looking at the champion path. Sure, there are one or two things that work okay, but until a Gunslinger can reload as a free action any mythic ability for that gives an extra ranged attack isn't exactly useful. Think of this. A Musket master, at his prime, can reload as a move action (until he gets the lightning reload deed). Which means he can use his power, reload, and then shoot again in one turn. Pretty good. Except the next turn. What if he wants to do it again? He can't, because he has to reload first. Or what if he shot the round before? He'd have to reload first. Basically, until a gunslinger can reload as a free action he can only reload once a round.
I'm not saying they aren't useful. I'm saying they become a lot more circumstantial. Granted, a gunslinger can take a different path, but there really isn't much, is there? Champion gives the few good abilities for ranged. Maybe trickster or Marshal, but one is really about focusing on something a gunslinger is only marginally good at (sneaking and things like it) while the other is good at helping other people. So a gunslinger who wants to focus on himself isn't left with much.
Maybe a few additional powers to make gunslinger and range in general a little more interesting for mythic paths? I can see a few ways to do this. Rapid Reload (Mythic). Downgrades every reload action to a free action. A very circumstantial feat, but useful. Maybe some more powers for ranged attacks. When I saw Guardian, I was hoping there might be something that I could work out a Guntank with. Would be interesting. Or trickster with a few more stunts that are more broad. Like being able to do trick shots or call shots or something. Hell, maybe a whole knew path to make the daredevil ideas more interesting. Abilities that make it easier to do something daring and awesome, relying on luck and, dare I say, grit to accomplish.
The gunslinger is one of my favorite classes. I always thought it got the short end of the stick when it came to how it was eventually made, but even then it has a lot of potential and you can see people working on it. I'd like to see more going forward for the gunslinger as well.
The Musket Master can reload as a free action at level 3 if using alchemical cartridges.
I would expect a fair number of Marshall Gunslingers to come around as it has very strong appeal at all levels. Alternatively, Guardian can be a solid choice for the tough guy, Eastwood-style Gunslinger.
It's likely that the Champion will have some more Gunslinger-friendly path abilities in the completed version.
Man what
Rapid Reload (Feat) + Alchemical Cartridges (Ultimate Equipment/Ultimate Combat) = Free Action.
No Mythic required, dawg.
Try being a witch you more or less have to be a mix of heriophant and archmage so that first feat is prepicked bleck.
