Before the Fishing Rod technique came into play, people learned to deal with this. There is no reason we can't go back to the way it used to be.
You haven't actually made a valid argument against the fishing rod
Your two points so far have been:
-"It takes no skill" which is just downright not true.
-"Why can't we just make it go back to the way it used to be", when people started using the rod tactic less than 6 months after MCSG came out.
The rod adds so much to the game. There was a time when it was removed effectively from the game on hive since you couldn't quick switch between items and begin hitting people, and everyone hated it - a lot of people moved over to MCSG until it was changed back. It took a huge amount of skill out of the game and made it more ping-based.
Honestly, I'm fairly sure the only reason you want the rod taken out of the game is because you're not that great with it yourself and don't really understand it. I say that because no-one I know that actually uses the rod at all thinks it's a bad thing.
