For the nexus map the thing I've seen someone post on reddit that looked good was figure out a decent space right next to your nexus in one direction, and build a lattice there, basically 3wide 4-5 long, then link all this shit together. You need the right pieces and islands spawning might fuck you up so you need to do it well and as fast as possible. You go through the middle to activate the sides without stepping in them(so they keep their full charges), preferably you use 3charges tiles, then you replace the middle once you're done. And then you basically run whatever the other way. Any modifier you hit will go back through the nexus and buff the entire lattice. Get like 20mods or whatever in that fucker, then run all that shit, then rebuild it again and so on.
The good thing is once it's setup, you can kinda forget about it and just run whatever you feel like using all your blocks. Setting it up takes some effort though.
