Abyssal on endgame

I really think it would be considerably more interesting if Abyssals weren't in all of the freaking maps you pick.

It's actually kind of fun to get abyssal on an endgame map, it can feel like an all out war.

But the problem is that if it happens all of the time, then instead of a cool "all out war" , it's just the same as the previous 10 maps you played.

The Abyssal mechanics are also really annoying. Which is okay in low doses.

If it was something like 15% chance it would be cool. Also, shouldn't it have an icon like Breach, Delirium, Expedition, etc?

Abyss is the current seasonal/league mechanic so it occures in every possible zone.

Next season/league it will probably end up like breach, delirium, etc. and the next exclusive mechanic will be in every zone.
