The old way was much worse.
Originally, the forts and keeps gave the enemy team a huge chunk of XP, which would go right into widening the level gap between teams… And anyone here knows that once a team gets far enough ahead in levels, then the chance of a comeback gets harder and harder.
The changes that you’re complaining about were made to remove the outright advantages gained from a lump of XP hitting the enemy level bar, but still make taking forts and keeps an advantage to the team that knocks them down and a problem for the team that lost them. The XP gain was spread out by giving a small bonus to the passive XP that both teams just naturally get every second, and also generated pressure for your opponents by now having a stronger wave.
The basic reason for these changes was the fact that the game is designed to be something where you must actually engage with the game if you expect to win. You have to be deliberate with your actions, use your resources wisely, coordinate with your team, and manage the situation at hand.
If you are not able to get either globe in a creep fight, I don’t think the problem is the mechanics… I think you’re getting bullied out of lane by a player forcing you out of lane like a player should do to their opponent. We can help you with that if you can give us details (what characters you play often, who you are up against, are you with allies or not)…
The catapults create lane pressure… Originally, at the start of the game, if both sides just sat still and let the waves just duke it out, the game is at a stalemate. There might be some wobble back-and-forth on the lanes due to some random glitch, but no towers will get damaged and none of the gates come down. The players are the ones that can alter the balance by killing minions and using abilities to push… Now, if the outer defenses fall, that adds a Catapult to the waves periodically, and as a result starts a very slow and very manageable erosion of that same lane. In order to balance it BACK, you have to take the enemy tower in that lane, send a hero to push the lane back, or pull a creep wave to counter-balance.
The ultimate reality is that, if you are really getting bullied out of the lane you’re in so you can’t get the globes, and if you’re also losing forts, you’re likely just not putting the right priorities on the right things to earn victory… Without details, the response really just has to be ‘git gud’, because you have to learn the basics of the game. Otherwise, if you give us details, maybe we can help you.
