Goal: Allow people to more quickly optimize their provinces to how they want them for war, this should make land dropping unnecessary and make the top more competitive.
Science: You have 100 science points to allocate into your bonuses. Make the max into a single category 50 points, and have it on a curve as it is now so that putting 50 points into a single category is not a great use of points. If you decide to change your science it will slowly settle to the new level over 72 hours.
WPA: The biggest complaint most make about growth is that they can't keep wizards up. This is understandable since it is not uncommon for a province to double or even triple in size in a war. Currently this means the KD must wait a 1-2 week for the provinces WPA to get back to the same level or they can land drop. As a result the top 50 is not nearly as competitive as it should be. Allow wizards to be purchased. 1000gc. (half price for mystics). Guilds will be given a small WPA modifier similar to thieves dens (mod = 1/2 the thieves dens mod works in my mind). They will still effect spell duration in the same way.
EoW: Winning a war will result in you gaining 10% honor based on your opponents end of war honor level. You will also gain 5 acres for every hour you were in war up to a maximum of 12k acres (96 hours*5acres*25 provinces) These new acres will be applied to your smallest provinces first, it will likely result in you having several provinces on the same acreage at the bottom, with your top provinces gaining nothing.
