You can't forget he slow arm time making it difficult to use for offense.
its barely even a problem
the amount of ground you can cover vs the stock makes it superior
are you one of those sticky slingers?
you have to aim at the ones that you want to explode instead of being able to explode them from wherever the forget you want
see: control point
you see that the opposite team is capping and you remember that you left some stickies there
just look at the CP for a split moment and right click?
having to look at stuff to detonate it make it better, you can also see where all your stickies move to and it allows you to take out multiple enemies from different directions rather than just wasting your entire trap on one scout bonk scout.
