even with shield skill 12 or 13 archers are able to hit you with frontal attacks.
That is bullshit. I can hardly ever shot some in his hight foot wich is most exposed to attacks from range. Giving headshots to shielder is impossible if we are standing on seme levels (and shielder have about 4 shield skill and proper shield).
You are also talking about that force fields are to small. You only forgot that most of round and triangle shields were made for not stopping arrows, but frome taking hits from melee. And force fields on horseback is hilarious. Shield is also covering sides and frontal part of horse, sometimes it's impessible to slash HORSE bacause shield is getting all hits.
As someone said force fields on small shields is ridicilous big. For bigger shields they are good.
You are also whining about weight of shields, and that they are too heavy. Shields were made of wood, steel and leather, and they were preety massive to be strong enought to be able to take hits.
In this game Long Bow is 4 kilos what makes it heavier than morningstar and same weight as Flamberge, and one stack of arrows is 10 what is equal to weight of Heavy Board Shield.
So if I would like to make shielder and have same equipment weight as an archer (as an example I'm taking myself) i should take 2 Heavy Board Shield, morningstar and a Broad Short Sword, but I can't do that because of slot system. So Shielders argument that shields are too heavy have no sence.
If you are a shielder and want to catch an arrow with your shield you have to face an archer and do not show him his side and back, it's simple.
Amount of archers is preety high, and archers are able to cooperate and help each other, maybe shielders and other melee should start also cooperating?
