Buff / production =equal values

Dear all
Each want the best out of the game = I can buy (gem-wise) glue-buff to get the Science bottle-neck bookbinder-books running + optimized = 01 issue crazy to invest on 24H-36H buffs IF I cannot fill the production lane with a production of almost equal time = Most of players also have a life beside game and it would give the Settlers-online more value for player + owner = thus improvements for both sides = please give it a thought not only for this prod in sale = but equal re-analyze many products in sale = Fun+money is acceptable - Kind regards to the whole community>Donni
