Do we need it? I mean can we just do things we want in the Condition function ? (Like what we do with Filter function in GroupEnumUnitsInRange to avoid using ForGroup)
Do we need the "Do nothing" function? Many functions are just there because somebody wanted them to be implemented for reasons beyond our comprehension or to make it look more "finished" maybe.
A trigger condition cannot use waits. But independent from that, it's just some sort of organization to interconnect dynamic codes and for semantics. The worst thing, you can do, would be to replace TriggerAddAction by TriggerAddCondition directly inlined. Because that's not what it stands for, you do not want to just put conditions.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
