Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Suggestions and Feedback Invisible sneaking is broken?

So, the tactic is simple:
-Fight starts, do some damage to the enemies and use invisibility at the end of the turn
-Go to the enemy "blind" zone and use sneak
-Wait for cooldown of skills while enemies just standing almost still (casts buff or some usless AOE in usless spots)
-Repeat
Is this work as intended? Because it's strangely easy to walkthrough the game by "assasin" or just invisible+sneak. "This seems to be broken" to me.
