This might not be the best idea but I've decided to share it with you because I don't think I've seen it here.
Whole point of it is to remove force field completely but give shielders one special buff. Instead of gaining force field by leveling shield skill they would lower the weight of their shield and at some of higher levels, but still reasonable it would become zero weight, practically the same as if they were using 1H no shield or twohander/polearm.
However, there are some issues:
- bigass shields (Huscalr) would become OP so it would be needed to raise weight of those shields so they never become zero weight
- archers would be able to shoot through shields more than ever, but I don't see this as a problem because shielders would be able to catch with them
- it's not realistic
Now, good things:
+ shielders could start wearing more armor, actually will be forced to
+ light builds using bucklers with ton of shield skill (forcefield) would become useless
+ hoplites using huscalr could be killed in a lot less time than now
+ it would force players to actually move their shield a little bit, to be able to deflect ranged projectiles
As I said, it might not be the best idea but its different
I like the intention of the idea and with some adjustments it could work.
However, as the suggestion stands now, it would reduce playing a 1h/shielder to practically 1h/board/manual blocking.
It would take away the shielders niche, as it would allow people to hit around shields even more than they do now. It would be practically impossible to defend a gate/doorway/bridge with a shield. Defending against ranged would be nearly impossible, taking away one of the few advantages shielders have now.
Sure, they can't catch archers now. But they sure as hell won't catch them after either.
Less shield weight means more room for heavier armour as you said, but that won't change anything in the archer catching area. So you contradict yourself a bit in that regard.
There's no difference in archer catching ability as it is now between 2h/pole and shielders because the first have more points to play around with and can get 1 more athletics easier. There's a ton more 18/21 2h/poles around than shielders. Your suggestion removes the advantage of a shield partially and gives a very slight runspeed bonus.
I don't have any suggestions on how to improve on your idea atm, but I'm sure others are more creative than I am.
