On practicality and efficiency with dual weild...
The devs will need to implement some kind of dual weilding mechanics to get it to work right. example the left and right mouse button for individual hits. to take advantage of dual weilding means independant arms aiming at different target and doing different things. eg aimed at two persons at once to both his sides (ie in 48 min trailer, jackie points at both royce and another scavenger), pointing up + down, mid+upwards etc, in short versatility. ive never seen this implement in fpv games (i welcome someone quoting a FPV game that does). so far its just aim at one point reticle and click. This means we dont use dual weilding to the full extend we would as we would in rl or in VR where we can independantly point and do exactly what we want. i may have seen it with auto aim in another game somewhere, that can work, still its limited to forward view.
as for now dual weilding works almost same as single weilding in a fpv game. point using the reticle, and click. just animations are varied with types of strike/block/kill, but still in a forward view. I know theres game like skyrim and others where they do individual button for attack/block for each hand depending which side u hold the shield or sword and i know it can work. but its still forward view.
Apart from the double damage, dual weild is effective if u can strike/shoot with one hand someone in front while silmutaneous strike/shoot at another behind u. i'm not wanting to sound like i'm a kind of know it fight instructor, but those who are just gamers and played vr titles get my meaning. theres more freedom in that sense. I can shoot to one side while pointing at the other. Hopefully u get what i mean.
Dont get me wrong, yes dual weild can work in FPV(weve seen it), yes i do want it in the game, yes i imagined playing a scene where v is on that bike and Im flying off it shooting at militech. im just saying that currently what i've seen so far its mainly used for double damage. and yea i know its so badass like doom or serious sam to dual weild giant mgs, and holy hell the destruction is incredible. Yes I've also played dying light where u can hold a button to look backwards while running and shoot or throw stuff, takes getting use to, but do devs want to introduce something like that? idk. then theres the targeting system like weve seen in red dead etc. some more one can we have one hand with a katana striking and blocking at the same time the other hand shooting? that was the cyber ninja i wanted to build. however again this means implementing a dual weild specific mechanic for the game. though making a whole dual weild mechanic so close to launch date? and polishing it? idk.
in the end, for this moment, if id want to argue practicality? i'd be happy with just the traditional dualweild point and shoot. it does look bad ass.
Happy to hear others with dual weild in game experience, I know ive not seen all types.
my 2c.
