Thanks for this base design, I've been switching back and forth between Trion and Mantis, and I don't think I ever got 3-starred when using Trion.
Usually lost 2-3 storages at most, whereas I got cleaned a few times with the Mantis.
I find the Mantis to be a little bit better at protecting DE though, I guess this is due to its original and confusing design, that sometimes results in total fails.




Thanks bro
