Maybe drop it to 10%, or remove it altogether and give Republics a different bonus. Due to the stagnation of grabbing on alliance based servers, all-explore republics are way too common. Unless we figure out a way to make all-explore less powerful, then the Republic explore bonus needs to be toned down.

Right now, on the alliance server
Evo has 32/53 are Republic
Fire has 5/15
LaF has 20/47
Monsters has 14/21
NA has 30/86
Sanct has 14/42
Omega has 23/39

That high a portion of an alliance all being Republics shows that Republic is a bit too strong right now.


edit: Specific suggestion of replacement bonus & penalty from lower in the thread
-50% building costs and +20% Military losses to replace +20% exploration rate and -10% military strength
