Hi, I'd be more then happy to provide my setup. Just know that each setup is for each person, it's a little hard to recommend. However, I'll state my reasonings so that you can have a basic feel and customize it to your own.
I also set up my Skill Layout to compliment the location of the button, you'll notice this as you visualize this post. I do this to help my brain memorize what skill is on cooldown, as it's much easier to register what button is on cooldown rather then work out what skill is on cooldown and then which button that skill is. Some skills also look extremely similar I find, so this also gets rid of that problem.
D-Pad = Up, Down, Left, Right - I use the D-Pad for movement due to the fact that movement is more fluent and simulates a keyboard well. Analog sticks are very touchy and can easily cause your death or ruin your dodge, the controller is also extremely comfortable to use with the D-Pad when moving around for the rest of the buttons.
Left/Right Analog stick - Mouse - recommended Right Analog Stick if you console game often: this is because players are used to moving their PoV while moving around in 3D games, so moving around your mouse during movement is optimal. I suggest mapping your mouse simply because it gets rid of the need to constantly switch from a 2 handed controller to a mouse with ease, it's easy to get used to and highly effective. Also, you'll need to map the stick to allow diagonal movement as well for more smooth mouse realism.
Other Analog Stick - Mouse/Pots - recommended Left Analog Stick if you console game often: this will finish the mouse and allow you to use emergency potions. Make sure to make this stick Directional only so that you don't get bothered by a stick's sensitivity.
Up - Left Click
Left = Health Potion (1) - you may also place a skill here.
Right = Mana Potion (2) - you may also place a skill here.
Down = Right Click
X/B - Jump - (Map to X on custom skill layout) - X is easily accessible and fluent to hit during combos and with combinations with skills.
Square/Y - Normal Attack - (Move to Z on custom skill layout) - Square is easily pressable with conjunction to Jumping and Moving, also with conjunction with shoulder skills.
Circle/A - Mana Break - (Move to D on custom skill layout) - Circle feels awkward to use and can be pressed, yet not combined, with other buttons. Since you do not need to press other buttons after mana breaking.
Triangle/X - Dodge - (Move to F on custom skill layout) - Triangle is easily to input alongside direction, yet can not be done with conjunction to jumping and skills, so Triangle is recommended.
R1/RB - Versable Skill - (Move to C on custom skill layout) - An example would be Knives for Seulbi or the first skill on Yuri, this skill is easy to access and easy to use and maneuver with, this is the most comfortable skill to use so it's recommended to place a cheap skill that you use often here.
R2/RT - Heavy Skill - (Move to T on custom skill layout) - An example would be Bus Summoning for Seulbi or the ariel shooting on Yuri, this skill can be used easily in a flash when the situation calls. Seulbi's bus is great for breaking super armor, while Yuri's ariel shooting is great for dodging. This button is extremely comfortable to use while moving.
L1/LB - Dodge Skill - (Move to R on the custom skill layout) - An example would be Lightning Ball for Seulbi and the "Rushing Sword" for Yuri (she slashes then comes back), this skill is not easy to use while moving, however it's very easy to switch back to moving right after and it's easy to use in midair. These skills will allow you to jump back after use, thus giving you time to switch your hands.
L2/RT - Midair Skill - (Move to Q on the custom skill layout) - An example would be Lightning Rain for Seulbi, this skill will need you to pause during use and is easy to use in conjunction of MidAir, best to use a skill that surrounds you.
Select - Escape - used to close menu, can be replaced with a skill.
Start - Heavy Area of Effect Skill - (Move to R on the custom skill layout) - An example would be Ultimate 2 on Seulbi or Ultimate 1 on Yuri, this skill gives you time to reposition your hands and is awkward to use, so it's best to use surrounded/away from the enemy and to last a bit.
Left Analog Click - Awakening - (Move to SPACE on the custom skill layout) - Easy to use yet not often used at all, Right Stick is a comfortable place for awaken as you don't want to mix it up with skills.
Right Analog Click - Combo Skill - (Move to V on the custom skill layout) - Used in conjunction with direction, however recommended to start combo's with. An example would be Ultimate 2 for Yuri or Counter/Ultimate 1 for Seha.
I truly hope this example has helped you in any way, and that you enjoy playing CloserS online!!
