The defense building researches should be also done in levels just like the troops and when reaching a higher level the selected improvement improves eg: faster shooting shoots faster at level 2 than at level 1 and damage over time increases from level 1 to 2.
There should be 3-5 tiers for each of these. The higher the elixer cost for each level.
