Idea with Gravity Well generators

Hi, I am a rebel/CIS player but I've always found the interdictor interesting. (it was one of my favorite ships in Empire At War). So this is the list:

Name: Speed control ahead Faction: Imperial Commander: General Romodi

Assault: Rift Assault Defense: Rift Ambush Navigation: Minefields

Interdictor Suppression Refit (90) • General Romodi (20) • Hondo Ohnaka (2) • Proximity Mines (4) • Grav Shift Reroute (2) • G7-X Grav Well Projector (2) = 120 Points

Interdictor Suppression Refit (90) • Admiral Titus (2) • Proximity Mines (4) • G7-X Grav Well Projector (2) = 98 Points

Onager Testbed (96) • Intel Officer (7) • Ordnance Experts (4) • Veteran Gunners (5) • Orbital Bombardment Particle Cannons (5) • Cataclysm (5) = 122 Points

Squadrons: • 6 x TIE Fighter Squadron (48) = 48 Points

Total Points: 388

So basically the idea is very simple: 1) Bid for second player, 2) put grav wells on the sides of the deployment zone, so only the very middle is outside of the bubbles, and 3) move the obstacles with mines to the center. So, no matter what will the opponent chose, the middle of the play area will be packed with mines obstacles and unkillable mins or a Rift. Or they'll have ships starting at speed zero. One is not a big problem, they start with that, increase speed to 1. But if more of them are at speed 0, Cataclysm will have some fun time. Let me add a picture how deployment looks like. Thats the minefields setup. No large ship can fit at the edge of the deployment zone without reducing its speed to zero. The Rift objectives would look similar.
