Why do tanks have so many skills?

[Maneesha]

hotkey mapping is for everyone different, i dont have any issues with the amount of skills on any class simply because i am used to games with a lot of skills to press.
i use "q,e,r,f,v,c,x,y("z" on english keyboards),<,^" as hotkeys since they are very close to "wasd" and i can all reach with ease. also "strg" and "alt" modifiers bound to mouse keys.
i wrote this as it might serve as inspiration for you how you could map your hotkeys. maybe you are not comfy with those and need to find your own way of mapping. also don't be discouraged if you struggle in the beginning, you will need time to get used to the new hotkeys and to build "muscle memory".

best of luck.

War doesn't have many buttons, same for drk imo.
If you really want to play gnb, maybe you can change you keybinds that way :
- I use a azerty keyboard so for me it's like 1,2,3,4,5,e,r,t,f,c,x,v( i use zqsd to move). I use "a" and two mouse buttons (S4,S5) that are not influenced by ctl, alt or shift : they are buttons for spamming/quick usage (you can do this for the continuation skill).
Here's how it's like in the end :

It's not much but i hope this can help you
