naa, rebels use hero's as scouts, generally i use r2d2 for that, as for armies, i disagree! don't trust the tooltips too much, a nebula-b while great at taking out tartans is good also against vsd's and to a lesser degree isd's (as long as u end the engagement quickly!), corvette's are good against tartans, gunships i group with nebula's since they generally target the same targets, i keep the fighters in the back or go around the tartans, marauders i generally only use against stations or if the enemy happens to hbave too many capital ships close to each other. although it IS harder on rebel, but i find it more fun as there's a much greater variety in ships (and nebula's just look plain cool!) my general defense fleet (per planet) is 3 corvette's (replaced by 2 corvette's 1 gunship on newer worlds), 1 nebula (replaced by an assault frigate on newer worlds), 4 xwings, 4 ywings while my attack fleet is antilles, 2 corvette's, 1 gunship, 2 nebula's, 1 assault frigate, 4 xwings, 5 ywings.
