Conquest research costs are still about 3 times as high as they ought to be.
Also, please please please get rid of the 25% Heroes Cooldown skill. Much better to have a 5% energy cost or tower cooldown or +50 troops or ANYTHING other than Heroes Cooldown. If anything, make it 200% hero cooldown - so that movement cooldown is 1/3 what is current. Something actually worth it.
