I've LC in 2weeks.... It all depends on activness... I pw hopped the whole time an did quests to get xtals. Ppl say it's not worth it since u can buy pro paks, tru... but if u buy pro paks and still reset an get the bonuses, u gain double the amount of bonuses then a person buying pro paks an not reseting... Guess it all comes down to personal preference
When you reset, you loose everything except for crystals, nobility, propacks, and achievments. With resetting you loose all land, gold, buildings, allies, etc. If resetting after Low lands LC then you recieve a bonus to your stats. (Example: 2% Attack/ Def) This will happen the forst 4x you reset. You can learn more about resetting in Sexwulf's Post.
