What do you dislike in ATB Systems?

[DoubleX]

I don't see anything wrong with ATB systems, everyone be gettin' so picky these days it's ridic, yo!

...In all seriousness, I don't get why people hate on particular systems, and like one over the other. I just play the darn games

Maybe because different players/developers have different wants and/or tastes.
Some wants to play speed chess, some don't want to deal with space management, some want to command an entire army(which would be TBS or similar stuffs), some don't want to waste time on waiting the atb bars with slow refill speed to refill from empty to full...(etc)
When talking about things players/developers dislike in ATB systems, it can be about the entire ATB concepts, specific ATB systems, or even specific uses of specific ATB systems.
In some cases, the entire ATB concepts might just violate the major targeting audiences' expectations; In some other cases, it can be some of its specific implementations that disturb most players.
So I think hating ATB systems are completely ok, as long as there are clear subjective preferences/objective reasons behind it lol
