Nah, just means more time spent wondering where the heck they are going to stick you. Reserve time will still be based on your relative seniority in base when you hit the line. Generally, Shuttle seems to have the most time spent on reserve, then CHQ, then Republic. All of that is driven by growth right now. Attrition seems even across the board.
XJT was leaving guys hanging on paid vacation for over a month while they were short IOE captains. They weren't assigning bases until you got IOE, so you couldn't get the move over with in the middle even if you wanted to.
