I recently picked a Secret Knowledge but i have come to find out that the Attack, Defence & Fortress only scale 5%-10% and really you should be Only looking at the troop types, they offer up to 100%. Your missguided into picking a tree that will not help you as much as another.. then asked for 3x the boosts & mats to do another tree.. Really!?! I pay alot to this game. There must be a way to have my Secret knowledge reset.. i only put a few points in. Seriously cant belive they do this to you at an near end game point just to milk you for money if you mess up. :(
