You have a 3 seconds window for reuse for certain abilities and a second or third charge for other abilities that won’t go on CD until the last charge is executed.
No need to increase the number of abilities/skills and talents I guess…especially with all the bugs that could bring.
Only this mmo game has extremely frustrating unfun combat because most of the time your target isn’t gonna stand in your face for you to manage to land a hit unless it’s a boar.
