The funny thing is, I always semi-jokingly said that the main way to win hightower is to do completely spawncamp the other team. And it's kind of funny that you're agreeing with that. I wish that wasn't the best strategy at the last point but oh well!People being bad at high tower is basically what you're complaining about. The strategy for high tower is pretty straightforward. When the cart is at the first hill, you have to hold down the top of the hill so that it can be pushed up. When it's at the final rise you have to hold the high tower (imagine that) and the top 2 spawn exits. When a team is even semi-coordinated it's fairly easy to do.
I agree with this. If hightower was one round, and/or had a forced 10 minute time limit with karts moving themselves, I think I'd be happy even if it ended in a tie.If hightower was like nightfall with a timelimit and overtime pushing the carts, I'd love it. That's my biggest wish in general: more payload maps with forced overtime. I just like the idea of the cart moving whether or not anyone is on it, so just deathmatching doesn't cause the game to stagnate. It's also why I enjoy Stage 3 of Panic.
