wau, like Fed mission tree that you have to do enables you to get a shield that has 4200 shielding or 3600 with -20% disruptor resist.
if i remember it right, but also those shields are sold in Exchange. one of my friend bought a T4 shield from there was around 70 000 ( i told him he was lucky ).
bloodlance, have you even played the higher tiers? 4200 shielding is nothing when a single cannon can produce over 2000 dps. damage is so high that you need to react just as fast, if not faster than, mastacowz said you need to. at higher tiers its not shield power that keeps you alive, its abilities and fast reactions from teammates and yourself.
