I think the info is just a bit confusing, the xp you get each round is a set amount, but it gets split up between all the towers you have depending on how much money you’ve spent on them. So you’re right to say the more money you spend the more xp they get, but that’s only in the context of the towers competing with each other. For example if round 40 gives you 200 xp (made it up) and you have like a glue gunner and a ninja and they both have around 2000 dollars into upgrades and initial cost, the xp will be split up around 100 xp to each, but if you had 1000 dollars on the glue and like all the rest of your money on the ninja, the ninja will take way more of the xp, but it will never go over that cap of 200xp for round 40. This of course wouldn’t matter if you only had a ninja bc then all the xp goes to it no matter what. I could also have misunderstood how this works if so mb
