Basically, I just wish a double weapon/double shield mechanic could be made.
A person could choose between holding two weapons, and having no protection, (although the shield canceling techniques could still be kept, you just wouldn't have the actual shield) which would give you double damage. (speedruns) the charge attacks could be changed up for a double weapon attack. Brandishes could have like a diagonal burst, or maybe going forward and backward, pushing the enemies in front and back. Sealed Sword could do like a 6 projectile attack on the front, or sides. Blitz Needle would have and incredible damage output if this could be made. For bombs, maybe the whole bomb mechanic could be changed. With 2 bombs, maybe the CTR could be almost instant, or just go back to the instant place from the beta, but still keep the damage and radius?
Shields on the other hand, would have a very small damage output, and maybe like a new mechanic could be implied with them? Like, the knight could turn into a rock if he has the Stone Tortoise or and of the tortodrone shields, and roll around, stunning and dealing area damage to enemies. The double-shield would be more a supportive party member person, where he would have the ability to put up the 2 shields and make the "red-line" type of shield that mecha-knights have. Or maybe he'd have the same abilities that a guardian has in lockdown, except doubled or something.
All in all, I think this'd be a great way to add new farming techniques, and speedruns for the game. The whole "double-shield" and "double-sword" thing could be like a mission that would give new players a choice in which "class" they could join. As for players that are already playing the game, they could also just do the mission for the same choice. You could choose between Classic:Sword and Shield, Offensive:Double-Weapon, and Defensive:Double-Shield.
It'd also work just like sprites, where you could by a class "ticket" or "pass" that would allow you to use either or both of the other classes too. Becoming a vanguard could also maybe allow you to use all classes... What are your thoughts everyone?
Is this suggesting for new weapon lines and mechanics, or saying something like "you have two weapons from your arsenal which are already balanced around only having one, but now they are active at the same time effectively making two clicks kill anything"? Because the latter is how dual wielding threads are typically set stated, and is something we really don't need.
An overall way to make dual-wielding work would be to lock weapons at their 4* power level (appearance-wise, too), and make sure they don't overwrite your shield. On top of that, reduce damage, increase charge times, and give an attack speed decrease. Potentially even add a movement speed decrease while holding the weapon. Two weapons + a shield is clumsy, but in the end you're getting twice the hits out in a quicker span of time. Depending on how powerful that turns out, you might even have to just make players swing 2/3rds or 3/4ths of the new swing total. With enough stat boosts, you'll make the weapon competitive with their stat boosted 5* versions, and still play differently.
I would say limit your weapon options however. Only specific weapons would have this capability.
Weapons I would include in the type of dual wielding I listed would include:
Sword: Winmillion, blazebrand, blizzbrand, silent nightblade, hunting blade, vile striker, ascended calibur, cold iron carver
Gun: all antigua, all blaster variants, all alchemer variants
Bomb: graviton bomb, electron bomb, all shard bomb variants, master blast bomb, irontech bomb
On the topic of bombs, bomb charge times would be doubled, however you could place a single 4* bomb at half charge (indicated by a blue charge period and glow around your knight), and an increased intensity version of the bombs at full charge (indicated by the yellow charge we all know). Vortex bombs would increase their suck radius by 50%, and damage by 100%. Shard bombs would increase the shard count by 25%, damage would be increased by 75%, and the shards themselves would damage enemies on touch like a tortogun charge projectile. Blast bomb variants would have 50% more range, 50% more damage, and would have a huge knockdown/flinch capability on top of their high knockback. I hope you like seeing gremlins fly.
Overall, weapons would have similar attack styles, but 3-hit combo weapons would have a 4-5 hit combo and a unique charge attack, and 5-6 combo weapons would have a 8-10 hit combo... Alchemers being the odd one out and only being boosted to a 3 hit combo.
Now, double shields? That's not something I've seen suggested before as far as I know. I really don't see the point of them, especially since weapon + shield is a great formula as is. Having shields on both arms might be kind of neat though, and potentially provide more defense at the cost of movement/attack speed. Think of it like adding ancient plate to your shield for 50% more defensive power at the cost of some of your offensive power.
I guess bottom line is that the formula we have right now works the best way it could for this game, however reimagining what can be included while keeping to that formula is always welcome.
