I’m a big fan of cost mechanics as a rogue. And wish rogue was more punishing with them like it used to be.
I like the idea. Could open the door to unpruning more CC and other toolkits if you made things cost and effect. Not just cooldowns.
even the notorious deep freeze had this. Fingers of frost caused your next ?frost? spell to treat the target as if it were frozen. This meant you could ice lance a target for shatter damage (like you can now) or you could deep freeze. (it also worked on frost bolt iirc. not sure.)
mage didn’t have icicles, comet storm, orb, and that niche 2 second nova that’s mostly a targeted shatter.
They were making a choice to trade damage for CC. Although, specifically with Deep freeze, it was also damage lol. If it was on kill target deep freeze acts as a freeze, meaning mage could shatter. But the choice to use it for CC rather than damage wasn’t rare.
You could also look at something like defensive cooldowns.
Wrath warriors have a really impressive toolkit, Reflect, Disarm, Bladestorm, Shatter, Fear, Intercept, Intervene, Regen, Wall, Retal, Reck, Shield block, Commanding Shout? I think. I’m probably forgetting some.
but this was balanced by the fact that abilities had stance and weapon requirements. Arms warriors weren’t doing their big dam with a sword and shield equipped. If you walled up you were in turtle mode. If you wanted to swap back to a 2h and do damage, or needed to for the situation, your wall was gone instantly.
If you wanted to pop reck and go in, you were putting yourself in danger. Reck had a negative drawback, kind of like the non-used talent fury warriors have [Death Wish] currently.
This is also partially why prot warriors were such a pain to fight, because they didn’t sacrifice their offense for defense. They just brought the damage with their shield. And had stuns.
Kind of a nostalgic tangent here, sorry. But yeah OP i definitely like the idea of cost balanced utility. Trading damage for something, or trading defense for something.
But also, not for every class. Some classes should always be squishy, like rogue, for example. Rogues should do big damage at the cost of being squish as heck. Feint can stuff it. Subterfuge can stuff it. UNiversal combo points can stuff it. Give me a diverse, strong, toolkit that if I misuse it or get cocky i get 2 shot. Make me have to think about what button i press, not just if it’s on DR or on CD.
Edit: Another great example is Ret paladin. One of the most memed and feared classes in Wotlk. Wings was a huge offensive cd. But it put ret paladins on Forbearance. So if you really comitted to that kill, you couldn’t bubble. So you had to be sure thats what the plan was right there and it wasn’t going to backfire. To balance this ret was an insane utility for your team. Friendly Dispel, Auras, Blessings, and that damage.
Or just any paladin, BoP was a huge cooldown, and a huge strength, but it came with a drawback. Melee can’t go in? Melee can’t go out. Cancelling bop was something melee players had to know how to do if they didn’t want to just be afk in a bubble, unless the paladin played for them and traded another cooldown to switch what blessing was up.
