Turrets only take time and space to build, and are gained as a sub-option of a secondary ability of the support staff. Yes, they're not supposed to keep up with damage of other classes burning their actual class resources into damage.
That's kind of my point in that area. >.>
Throwing a Turret on smaller land really doesn't going to make them some kind of choose-all option, they are inferior in several ways to other Classes, except for range...
-Turrets auto-target closest, so that's why, instead of your space carrier, your vanguard should consist of either expendable mooks or the tough regenerating dude or high AC spec ahead to bait shots.
Doesn't matter. Like wise bringing up Alert is pointless since even Leadership can give you four of these and you still have four other, higher-level, Followers to choose supply bases and such. Heck in Bahamut's case Atomic Temple doubles this and we're talking about
a single character here, not a civilization over a hundred thousand people strong currently worried if another fraction is going to attack them or not or how a planet support several tens of thousands of these even at the noted "too high" land consumption rate. And wondering why a 20th level Ship Captain is fighting a 4th level Turret is really just you missing the point: All you
need is a single lv4 Torrent to successfully fend a 20th level character off.
Like totally ignoring the fact that Mech's don't move as fast due to Energy limitations, even at the rate of 360mu/rnd and needing one hundred rounds to kill a single "vanguard" agent, you need an army of two hundred and forty four of them just to attack a single low level base
addition. It doesn't matter if you think 8d12*8 isn't a lot or think that's one to many followers, it's the fact that a Turret has nearly twenty five thousand rounds to attack oncoming enemies and as a result even a single one of them at the lowest level possible is enough to wipe characters that are too high for your games off the map.
In Osl speak, when combat starts against your supernatural mecha-wielding mundanes the Turrent drops 8,147 Time Stops except he's able to attack during them. For a guy that hates magic, you created a binary railroad of "must have teleport to win". Their range needs some serious reconsideration. Like you don't have this problem with archers in castles because the archers can only shoot at what they can see and Spot has penalty for distance, likewise the archers incur penalties to attack rolls the further out a target gets as well. Turrets ignore both of these with a massive covered area.
