Abysses spawning in Boss Arenas

Am I the only one that HATES that an Abyss can spawn in a boss arena and it almost always gets me killed?

That should be a big priority of a change to the Abyss mechanic, if they plan to keep it passed just this season. Does anyone else have this problem?

It's been like this since the beginning and since they never fixed it you can assume it's intentional.
