Yeah, man, Pinnacle is one of the worst places you can work. It's been like that for years; I thought everybody knew that. A quick search on any aviation forum will tell you the same.
There's really no reason to go there unless you already have 3000+ hours and can be guaranteed a quick upgrade.
But even then, I wouldn't go to Pinnacle because regionals always lie about how fast their upgrades will be and then you're stuck working at a craphole.
