I've seen absolutely ridiculous workflows on Jira. Things like - "i'm gonna make the most ridiculous workflow out of spite and boredom just to troll you."

From that perspective it's easy to hate it, but you hate the actual use of the tool not the tool itself.

Currently i enjoy more sane use of it. Simple workflow. You get in, read the ticket, clicky a button, get out. Slowness in that regard is very tolerable.
