Indeed, the only thing they can hit when raiding is guard posts, and command stations. And while that would be fine with me, when I tried that, taking my 700ish Mk 1 and 2 teleport raiders in to take out a guard post, they got instakilled by lightning turrets and an autobomb. The post was down to 98% life by the time they had all been killed. Personally, I think they need more life. 2000 hp? Is that a joke? Teleport battle stations are far far more effective, both at offensive and defense in my opinion.
Makes me wonder why we even have teleport raiders, if they are just like battle stations only weaker. At unit cap, battle stations will do more damage, do damage faster, and live longer. They will also build faster, as you only have to build around 130 for all 4 mk levels, rather then over 1300. The only advantage they seem to have is longer range, but if you are teleporting right on top of your target, does range really matter?
As a simple test, I took a map, 991210938, that has both on it, and did two games. Ship cap of mk1 of each. With the stations, I was able to take out two systems, command stations, guard posts and Special Forces. With the raiders, I was able able to take out two systems, but the systems died slower. *shrug*
