I usually (almost every hero) use One (1) Bar on all of their skills. exclusively using my mouse's right click for teleportation or travel skill.
As both my pinkies and right ring fingers are missing... hahaha... this is perfect for me.
I see to it that every hero has the same "Key Binding" that corresponds to my fingers. As I have some fingers problems too. EX: my Cap and Deadpool's key bindings are as follows:
"Mouse Left Click": Basic/melee or range for targeting. (Heroic strike)
"[?]": Trash cleaner when far away (Range) Shield Bounce
"[>]": Trash cleaner (melee/up-close) Shield Swipe
"[<]": Vibranium Bash for Serum regen.
"[']'": Boss+trash or Hard single targets Airbourne Assault.
"[;]": Boss+trash or Hard single targets Meteor Kick.
"[L]": Boss+trash or Hars single targets Star Spangled Strike (Signature skill)
"Mouse Right Click": On your Left (Travel/Teleport skill(s))
"Space Bar" for Medkit
Here's my Gotk-less The Captain Simple Build: http://marvelheroes.info/build/38992/
Also my Deadpool here: http://marvelheroes.info/build/37237/
All my heroes have the same key-bindings and all uses one (1) bar skill only.
Hope these helps my fellow brothers !
Deadpool thinks this is considered as a "Constructive Thread Post."
