Showcase: The Alchemers; Weapon-Switching

For those who doubt the power of the Alchemers, I showcase them in a run of the infamous Royal Jelly Palace.

My controls were all keyboard:
Weapon 1: Q
Weapon 2: E
Shield: Space and Right Click
Attack: Left Click
Edit: Added Right Click on Shield and Attack config.
The Gear I used:
5* [Umbra Driver]
4* [Primsa Driver] Cause I am waiting for winterfest for the Nog Blaster :)
3* [Black Kat]
5* [Chaos Cowl]
Weapon Switching greatly increases the effectiveness of the alchemers and greatly benefit those who are advanced at gunning. Please beware; your hand will eventually get carpal tunnel but you will soon get used to it as I did. :)
Weapon-switching is basically in this order
1. Attack
2. HOLD SHIELD
3. WHILE HOLDING SHIELD: press E then instantly press Q to go back to your first weapon ; vice-versa if you are using weapon 2.
4. LET GO OF SHIELD.
5. Repeat
Thank you for supporting me.
Criticism and judgement is welcome for I am still learning.

What do you use for attack? And great play. +1. We can team up together in LD and spam alchs all day.
Alchs, imho, are probably the hardest weapons in this game to master. Once you master alchs, you basically mastered the core fundamentals of this game.

Tutorials like this are good. Please clarify your control system for me.
Are you using the keyboard for aiming? Then how do you aim precisely enough to land alchemer richochets?
Are you using WASD for movement? Then you can't move while weapon switching, right? Movement is my top priority.

@Bopp
Are you using the keyboard for aiming?
-No I am using my mouse for both aiming and attacking.
Are you using WASD for movement?
-I am using an unorthodox way for movement which I have learned back when I was playing World of Warcraft.
To explain my unorthodox configurations in a detailed manner:
*Forward Movement: W
*Back Movement: X and Mouse 4 (Extra button on my mouse: http://gaming.logitech.com/en-us/product/moba-gaming-mouse-g302 )
*Left Movement: Shift
*Right Movement: C
My hands when rested on my keyboard: *** Left Hand ***
Pinky Finger: Shift
Ring Finger: Q
Middle Finger: W
Index Finger: E
Thumb Finger: C and Space
People are going to ask why Mouse 4?
-It's really hard for me to strafe Back and Right (together) with C and X so I press C and Mouse 4 together to strafe.
Edit: TYPO; removed straight into strafe.
People are going to ask why you have two configs on Shield?
-When I'm strafing left and my thumb is occupied on C, instead of pressing C and Space in an uncomfortable manner I use right-click.
@Milly Souls
What do you use for attack?
-Left Click
Thank you for the nice compliment :) and I totally agree with that . Making a 2-shot weapon with a slow reload into an endless trail of high hitting bullet is immaculate ! I have never played Lockdown but I am up for trying.

Username is Millionsouls and I'll be honest, I'm not quite as great with alchs as you much, but maybe it's because of my controls and rather lackluster computer set up, not meant for gaming much.

@Bopp
Yeah it is very unorthodox but it makes the important keys (A;S;D;Z;X) open to further configurations. You are welcome :)
@Milly-Souls
I added you~! :) I'm pretty sure we are on the same level and thank you !~ You just have to find a control setup that you are very comfortable with but it takes a while to get used to a "unique configuration" for a lot of people since many games introduce you to either the traditional "WASD; ARROWKEY" configurations. Same I'm playing on an old refurbished Lenovo ThinkCentre. The only equipment that I own that is decent for gaming is the Logitech G302 ( http://gaming.logitech.com/en-us/product/moba-gaming-mouse-g302 ) and an awesome customized WASD Keyboard ( http://www.wasdkeyboards.com/ ).

My control scheme is really odd due to the limitations of my keyboard and mouse.
I use space for weapon down and down scroll for weapon up (when I have 3 weapon slots). WASD+hold left mouse movement, X for shield and right click for attack.
However with this clunky control scheme I can still switch weapons decently. It helps when I have just 2 slots and also Max ASI.

I think I actually have similar controls to you, Hycrime.
Here's what my keyboard and mouse looks like: http://images.anandtech.com/reviews/mac/imac2011/_DSC6134.jpg
WASD for movement.
Left click on mouse to action.
E is first weapon, Q is second weapon. Not sure about third weapon yet, but I've never had to really use a weapon slot.
Space is shield.
1234 for pickups
ZXC for Sprite skills
F for dash.
Tab for shield bash ( I never use this, lol, then again, does anybody? )
Arrow Keys for emotes, like attack! and fallback!
To be honest, I'm still kinda trying to look for the perfect control setup that'll allow for both mobility while attacking and comfortable-ness, but this works for me mostly.
As far as I know only beginners who don't know about the richochets of the higher star versions doubt the power of drivers.
