Starslayer and I have run into the 100 HS nightmare in our campaign, basically our average TL is now 9 and so you can deploy a fairly solid defence around any WP given time: BS4-6, small craft CAP, mine fields, IDEW and so forth. But 100 HS WP restrict you to BBs as your largest assault ship. Now we have home rules and such which make construction take a more reasonable time so no one can just shovel through BBs till the enemy collapses, or at least you could do that once only and need a long time to rebuild your WP assault force.
To solve this we are allowing Ic based battle rider carriers but still...the @ works far better with Jc engines were it is arriving at a distance to the WP...this is basically only a solution to allow SDs to move through WPs that they could not fit through normally. I'm still dubious even a CVB battle rider carrier is really going to be able to bring more than 1 SD or ML through on racks and not have it blown off said racks.
I was thinking to make a new engine available TL8. The engine would reduce the effective transit size of the ship mounting it (ala Galactic starfire) so that a SD can make it through the 100 HS WP but the first generation engine would only allow a transit speed of (max)-2 (so 3 SDs per turn). The next engine at TL10 would reduce the effective transit size so a ML could transit a 100 HS warp point and allow transit speed of (max)-1 (4 SD or 3 ML per turn). The last type at TL12 would allow a MT to transit a 100 or 180 HS warp point and allow a transit speed of (max)-0 (5 SD, 4 ML or 3 MTs per turn). During transit turns they could not employ engine tuners and would need 1 turn to enter or leave transit mode.
The next option is to make this an ability like advanced manoeuvring. So it is a zero HS engine modification you can buy for a cost increase to your engines. You take a turn to turn it on and off.
The final option would be to make the is device like a 2nd gen engine tuner that you need to install on the ship. It would then be active or not. It could not be run at the same time as an engine tunner.
What do people think? I'm more or less just trying to get some brainstorming on the subject. I'm a lot dubious the battleriders will work out for assaults though that will give some strategic boost to races that till now have been blocked from even deploying SDs due to 100 HS WPs.
