I have tried the strategy of using seekers to outrange weapon platforms, and even with all seekers (no beam weapons) and max. weapon range, the ships go into range of the planet (not too bright).
As for using tactical... well.. I only play on PBW, and you *can't* use tactical. Unfortunate, but the computer doesn't do a good job of using such specialized designs
Probably just stick to my boring, generic designs
To be honest, I haven't used the temporal tree all that much, as I've found that no weapon does more damage/turn than maxed out anti-proton beams, and they always seem to win out over designs using more unique weapons (in strategic combat)
