I need some suggestion...

2 OA is pretty much "light" armor in my book

Especially for scouts what will be facing off with the enemy in tiny skirmishes (1 vs 2-3) You'll want to load up on OA to perhaps half the space on your ship.
With enough regen, the enemy simply won't have enough firepower to break through, and you can take all the time you need to kill them.

IIRC, in SE4 classic, your OA will start storing up regen points right from the start of battle. The longer you delay before reaching weapons range, the more points you'll save up and the more invulnerable you'll be
