I would be fine with a hack duration reduction, but with that then her cooldown need to be reduced as well.
I like the idea of giving her a damage boost to enemies whom are hacked, but then people will start to complain that she is a quote on quote
Tracer2.0 meaning people will complain that she deal damage while being abled to “teleport and being invisible”
I do think her base speed need to be 6.0, while giving back her +75% speed boost, that way she has an ability to catch up to that hacked target, as she does not have an in combat ability like other offense heroes do.
As for the cast time, I was surprise when they invited me to that thread as I never knew that, however, I think the reason why it's like that is because in her kit she needs at least something that is consistent.
I am opened to the idea of reducing the radius, but even so that means she need compromising buffs that will objectively outweigh the nerfs.
I made some really good mega-threads with great suggestion, some are outdated, as I made it during the that periodically time, but I advise you to check it out and tell me what you think.
