It's more that enemy Servants don't have cooldown on skills, they can just spam it willy nilly, and there is a freaking reason we have cooldowns, things get out of control real quick if you can just spam, once during the Nerofest, I was farming Gold medals and I let the Waver live a little too long, before I knew it he had spammed Advice of the Strategist so hard that he was literally immune to damage, and without a Def piercing unit, there was nothing I could do but stall and hope he wouldn't use it as much anymore.

Any Servant with an invunerability skill can become problematic because of this as well, you can consistently get bad RNG that have them use it every round and become immortal, thankfully those don't loop their skills as much.
