Okay, so I have a decent amount of gold right now (Don't try it), and I'm at the point where I'm thinking that I'm too lazy to go further in the HL so I just converted 2 level 3 subs into 2 level 1 CoEs. Should I wait to get level 2? LLBC starting. Even though T4 level 1 is worth more than level 3 T3 sub, stat wise, does it affect plunder in anyway? Thanks in advance.
I did the same thing, I got to the 13b land explored in the highlands and pretty much just started converting everything to t4. not the WORST idea ever, but it definitely hit a plateau for a while. I'd keep exploring highlands just because each new building is more plunder (unless you build too many t4 or sos) and then convert buildings one at a time to at least level 2 t4.
