It makes fights long boring and drawn out. Also its kind of annoying their weapons completely ignore your shields most of the time and do hull damage. Doesnt make the game hard just annoying. In one fight an equal level ship in its first salvo of nothing but energy weapons took my hull down 20% then torps took it down another 20% yet I had full shields and weapons were normal phasesrs and photons and no special attack going by the combat log. and also the npc tatic of hiding inside asteriods so I cant hit them and they can hit me come on devs learn to program your npcs. Right now you give them so many cheap ways to win its not really fun. oh its also fun that enemy ships can fire plasma and other torps from broad side and that all thier weapons are 360 degree's .
I think you're becoming a tad confused. First, their shots do hull damage because of the bleedthrough. 10% of the damage per hit (5% with resilient) will hit your hull regardless of your shield status. And as for shields regenerating to full, they do but not nearly as fast as you put it. Dont' forget they use the same abilities we do at higher level, so you might see them pop emergency shield regen. Save your torpedos for when their shields are down, not to take their shields down.
As for weapons being fired from 360, I know for a fact that they have the same fore and aft arc as we do. Put it this way, try hugging their side while flying in a cruiser. You'll notice they will not fire a single torpedo at you. However if you get into their aft or fore arc, they'll fire them. It's a 90 degree arc so it may look like they're firing from the side but they arent.
And as for them taking your hull down 20% with full shields, you're probably trying to fight things much higher in level than you. Or you're being hit with a torpedo spread. Think of it this way, lets say you get hit for 4000 damage. 400 of that will go through even full shields (200 with resilient) to your hull. So if you get hit with a spread of torpedos from multiple enemies, then yes, it will hurt. The fact is, it will do the same if you and your teammates did the same to that one ship.
Instantly recovering shields aint a problem for me even as a cruiser Captain, what is highly annoying is the frequency with which the Battleships use `Viral Matrix' really annoying when you get yanked into a random combat encounter, decide to do it, only to find that 2 D'deridex Battleships are bearing down on you!
One pops viral matrix on me, its about to wear off whilst my shields are about gone then his mate hits me with another, both then hit me with `High Yield Plasma Torps' simultaneously, oddly enough I went BOOM! made me laugh though got totally wtf pwned, wasnt expecting them to do it one after the other then both hit me with torps.
There seems to be a very low cooldown on mob/ships using Viral Matrix i'm constantly being spammed with it when fighting Battleships, never used to be like that, methinks the Devs have been playing with it.
Add this to the instant shield recovery and as a cruiser Captain what you have is a long drawn out epic struggle to kill the damn thing, its nuts.
Against NPCs, don't even need science team. Just pop some sort of defensive cooldown when you see it incoming.
That said, the devs do need to improve ways of handling with it. A single team ability should be the way to get rid of it for everyone but escorts. The tactical maneuvers ability to get out of it should be moved down.
But back to the topic of shields...
Both NPC and player shields are a bit on the weak side, as you level up.
Player shield capacity just doesn't scale well. You're looking at a very small increase in capacity with each mark. Meanwhile, damage increases quite a bit, as weapons scale faster and they are impacted by skills and commonly used consoles. Regen is okay, since there are various skills that wind up boosting shield regen a bit. But capacity should scale at least2x as much as it currently does.
NPC Shields (as you get to the higher levels) don't scale well either. They have low totals, don't regen well. Makes them super easy to knockdown and you spend the majority of the fight going after hull. So they need to see a buff to capacity and regen. Basically, an undoing of the nerf they did to NPCs in beta.
