What to do with Broken Action Economy?

[Nettlekid]

I've always been a little unsure about this. Whether you're using a Swiftblade, Shapechanged into a Chronotyryn or Aspect of Demogorgon, a Planar Shepherd with a fast time Planar Bubble, a Beholder Mage, or an Ardent with Dominant Ideal Synchronicity abuse, you may have many more actions than your fellow party members or enemies, but what are you actually meant to DO with all that extra time? Despite having more actions, you still have a set number of resources to spend for a day. And just churning out Save or Dies, blasting, or wading into melee are all called ineffective methods of combat. People say that battlefield control tends to shut down battles better, and throwing up a few Walls of Force can be accomplished without needing a 10:1 turn ratio against your opponent. Especially in the case of someone who's spent a lot of build resources to get this action economy abuse, what's left to be done with it?

Save or Dies are ineffective means of combat? Since when?

Anyway, Action Economy Abuse is simple to make use of. The more YOU can act, the more you can do before your opponents do. What you do SPECIFICALLY doesn't matter; heal your party, buff and debuff, just straight up stab people....what matters is that by pure number of actions per round, your opponents are statistically screwed because they can't so much as break even.

It doesn't matter if your opponent can deal 200 damage a round if you can heal 50 damage per action and can get like, 5 actions per round. You know those videogame bosses you need to effectively stunlock because if you don't they'll manage to do like 6 horrible things before you can get a word in edge-wise?

You are that boss.
