I think we need a different angle on that topic. It would be really counterintuitve to give shields better dodge. They are defensive Tools and they should allow you to just stand your ground and take control of a situation. Additionally we have a ton of Traits, Talents and so on that increase defensive capabilities (like Block-Cost, Block-Angle, Stamina-Regen… etc.), most of which are pretty useless currently or are at least not really considered by a majority of people.
While Fatshark very often tries to be as realistic as possible when it comes to weapon design (even if it’s horrible for gameplay cough Kruber’s Longbow cough) I think they missed an obvious thing when it comes to shields: Shields provide passive protection, as you don’t need to worry about every single attack thats coming your way. You really don’t need to actively parry like you would have to with a sword (i.e. checking and aligning the angle of your blade with that of your opponents for example). This also allows you to block multiple attacks that come your way without too much of an issue, or at least compared to any other weapon.
So therefore how about just making shields passively block attacks from mobs. Therefore you could attack “while” blocking as mentioned earlies. Of course this would still deplete your stamina pool (maybe even cost more stamina) but it would give you more flexibility ingame. Shields therefore would so to say offer you two modes to use them: Either you go into full crowd control as you do currently i.e. by shoving/pushing/stunning using your stamina actively or you could just switch into an aggressive mode where you just throw yourself at a group of enemies swinging at them wildly and hoping that your stamina doesn’t run out before all enemies are dead.
Of course this wouldn’t be like IB’s Talent as it’s not an invulnerability. Overheads or charged attack could still break all your stamina shields at once as well. Also Attacks from outside your Blockangle will still damage you. Again it would just cover your frontarc.
This would justify the lower damage output as at the same time you just can take more hits and would bring in the benefit that all those talents I mentioned before would be far more interesting. Suddenly strange traits like Inspirational Headshots or other stamina buffs could actually help a coordinated team as maybe your ranged classes provide stamina to your tank to hold the line (not just bounce enemies around in silly ways waiting for someone else to actually bring in the dps needed). To me the current gameplay loop of shields, i.e. spamming push block just feels bad. When I pick a shield I want to be beefy and able to stand my ground, not play ping pong with staggered ratties.
PS: And yes that might make Kerris new Spear and shield combo OP but frankly I don’t give a sh*t. First Shields are kind of bad. Yes they are viable but I think gameplay wise they just feel weird. And also there are far worse offenders right now and also I think you could balance new weapons as well. Maybe the Spear Shield combo has a very low amount of Stamina compared to other shield combos. I’m still hoping they’re making more of a buckler for her rather than a towershield but we will see.
