Those were better than nothing, which is what we have now
but we have gotten so many more complex cards now that a legitimate icon indication method is sorely needed for the UI. Like you can see symbols for all buffs and debuffs at the top of the screen in Warframe, we have some cards that work exactly like their mods.
Warframe mod: Rolling Guard- on dodge, become invulnerable for 3s. 7s cooldown
Works exaclty like:
Spacelords card: Epimorphosis- 3s after being shot, heal 50 points. 10s cooldown.
Warframe has a blue buff icon that appears at the top when you activate Rolling Guard, with a timer counting down, and then it turns into a red icon during the cooldown period.
Spacelords already has an advantage in implementing these because every card has a unique icon graphic. Just have those exact same icons appear when a card is active, and if it has a cooldown, make it turn red or grey. Allow us to move our UI around so we can put it where we want it (UI customization has already been requested many times in the past, so a dedicated UI update would be awesome as a general statement).
