three more advices:
a) Scout ahead and get info wether the enemy is hiding a part of his fleet at the next gravwell. If so, do not let yourself get drawn into conflict at the edge of the combat gravwell towards the enemy. This will also help you in fleeing right in time.
Always max repair. Advent: Progen. Shield Repair, Hangar Shield Bestowal, Domina Subjugator Hull repair and +30 hull repair from Repair bay (if possible)... Tec: Hoshiko (20) and upgraded repair bay, if possible Dunov shield regen (helps lvl 6+ marza survive if MB got broken), combine with docking boons bonus (rare occasisons). ... Vasari: worst repair bay (15), but good repair cloud from Skirantra (20-25-30), btw use that to tank Malice and lum sidebeams, OVerseer with lots of antimatter. Only good thing for Vasari: larger cap fleets should have at least 1 Antorak Marauder with speed upgrade to get out if PJI is placed or escape is needed quickly...
c) if a cap has to flee, try destroying starbase first to avoid further hull damage.
