You would be incorrect I’m afraid! I am fixing my base from mistakes as an early player so I only have 1 tower that is in the 10% discount point at this time, several that are in the 20% stage and more in the 30% stage (but they are taking less priority obviously). I had about 3 wood packs last fort and had to grind out 15 mil lumber pretty much solo due to conflicting schedules with my team mates that week. It was hard and incredibly dull, if these changes had been rolled out I would have gotten an additional upgrade in. My main goal last fort was catching up my storage so normally I wouldn’t need to use quite that much but at least 6 mil wood was needed for my main attack towers which was a ballache to farm at 50k lumber a run lol.
I base my fort planning on desired tower levels that I want to achieve in line with my ability to kill enemies still, so under either the old or new scheme I will level exactly the same amount but now it will be easier for me to fix my base while using less resources. As well as that the discounted breeding means I will hit obsidian next breed which has saved me over a month of time compared to my previous estimates.
Everyone’s situations are different and I get it that this will affect some people who aim for just the 720k points with the least levelling possible but these changes benefit me entirely so I have no complaints personally. And I think it likely that there are many others in a similar base situation that it will benefit too.
However, if people are getting through the breeding tiers quicker than they should be able to continue developing in a similar manner to before.
Edit: Oh and no, we don’t have a castle so no Atlas banks
